Best HDMI Audio Extractors for Streaming and Game Audio

The best HDMI audio extractors for streaming separate sound from an HDMI source without forcing your TV or capture chain to handle every audio connection. If you stream games at 4K60 or lower and want analog stereo for an audio interface, the J-Tech Digital JTD-322 is the strongest straightforward choice: it offers an HDMI passthrough, optical output, 3.5mm stereo output and selectable audio EDID. The Insignia NS-HZ340 is an easier retail pickup option. For a 4K120 gaming display or a TV with eARC, examine the J-Tech Digital JTD-3200 instead, but verify the precise video features your display needs. These are research-based picks from manufacturer documents and United States store listings checked October 30, 2026; no hands-on tests are claimed.

Before you order: an HDMI audio extractor is not a capture card, USB audio interface, microphone mixer or device for circumventing protected video. Its optical output does not plug directly into an ordinary computer headphone jack. For OBS, the practical route is usually analog stereo into a genuine line input, optical into a compatible digital audio interface, or HDMI game audio from an existing capture device. If your capture card already carries clean HDMI game audio into OBS, you may not need an extractor at all.

Quick verdict: Which extractor fits your streaming setup?

• Best overall for straightforward game capture — J-Tech Digital JTD-322 (JTD18G-H5CH). Up to 4K60 HDMI passthrough, 3.5mm stereo and optical audio, plus TV/2CH/5CH EDID options. The practical limitation is the 4K60 video ceiling and lack of true surround-to-stereo downmix for incompatible formats.
• Best for local pickup — Insignia NS-HZ340. Best Buy’s 4K60 HDR extractor has optical and 3.5mm outputs and a simple audio-mode switch. Its appeal is ease of purchase and setup, not next-generation 4K120 gaming.
• Best for two HDMI source devices — OREI BK-21A. A 2-input/1-output HDMI 2.1 switch with optical and analog extraction and up-to-4K120 passthrough. It briefly interrupts the display signal when changing inputs; do not mistake it for a seamless live production mixer.
• Best for actual 5.1-to-stereo downmixing — J-Tech Digital JTD-3146 (JTECH-EXD-ARC). Converts supported surround input into two-channel RCA output when a stereo feed is needed, but its analog and surround capability must not be confused with generic Dolby Atmos decoding. Video passthrough is limited to 4K60.
• Best premium 4K120 and TV eARC option — J-Tech Digital JTD-3200 (JTECH-8KAE). Video passthrough to 4K120, plus optical, analog and dedicated HDMI audio-output choices and TV ARC/eARC support. It costs more and explicitly does not downmix multichannel audio.
• Best midrange 4K60 TV eARC bridge — J-Tech Digital JTD-3255 (JTECH-4KAE). Optical, stereo RCA and HDMI audio outputs with TV return-audio capability. Check seller-specific availability: the J-Tech direct store listed it as sold out while a Best Buy listing offered purchase.

Fast decision: if the only goal is an OBS stereo feed from an HDMI console, start with the JTD-322 or NS-HZ340 and configure the source for PCM stereo. If audio must be extracted while preserving 4K120 video, compare the BK-21A and JTD-3200 according to whether you need two source inputs or TV eARC. If a surround source must be turned into two-channel RCA, favor the explicitly documented JTD-3146 downmix function rather than assuming all extractors perform conversion.

Comparison table: Verified ports, video modes and US availability

Prices are exact US listings observed for the named seller and model, not universal market prices or price promises. An “Add to cart” listing indicates a seller was accepting an order when checked, but it does not independently confirm warehouse inventory or a delivery date to your ZIP code. Only the specific Best Buy pickup listing above showed explicit local availability. Where the manufacturer and a retailer disagreed on stock, both facts are retained. Stock and prices can change rapidly, so check the exact SKU and delivery options at checkout.

How we chose products for actual game and livestream audio

We focused on six specific, documented HDMI audio extraction products rather than adding passive HDMI splitters, simple optical-to-analog DACs or capture cards to inflate the comparison. The core job is to accept an HDMI source, continue video to a monitor or TV, and make usable audio available through at least one separate output. Each pick has a defined reason to exist: inexpensive stereo output, retail convenience, switching two sources, true downmix, higher-bandwidth TV sound, or a midrange eARC bridge.

The important research questions were output types, source-versus-TV return-audio behavior, maximum supported HDMI video format, audio codec compatibility, EDID settings, retailer availability and likely stream wiring. Manufacturer specifications established the model-level features; current US seller pages supplied individual prices and purchasing indications. We did not infer real-world latency, audio noise levels, lip-sync accuracy, cable reliability or picture quality from marketing language. A hardware claim such as “4K120” is not a lab result and may depend on display timing, color format and cable support.

For OBS, usefulness has a precise meaning: the streamer can identify where the extracted audio enters the capture computer, choose a compatible audio format, prevent duplicate game sound and record a clean local test. A product with more connectors is not automatically better. A basic extractor with an obvious stereo line-out can solve a game-audio problem more directly than a premium unit whose unused eARC and HDMI amplifier ports create additional handshake settings.

In-depth product reviews: Six distinct streaming uses

J-Tech Digital JTD-322: Best overall for an uncomplicated OBS stereo feed

Who it suits: a console or secondary gaming PC user sending up to 4K60 video to a monitor while wanting a dedicated analog or optical game-audio connection. The JTD-322 is also listed under the model identifier JTD18G-H5CH; checking both identifiers helps avoid purchasing a lower-bandwidth or different-port version. Its official J-Tech product information specifies HDMI video up to 4K60, optical output supporting PCM or standard Dolby/DTS 5.1, and a 3.5mm stereo output intended for two-channel PCM.

Why this is the primary pick: the output selection closely matches what a streamer needs. The analog jack can feed a compatible line input on a streaming PC’s sound device or an external USB interface, while optical can feed a mixer or interface equipped with a suitable S/PDIF input. The physical TV/5CH/2CH EDID switch gives a direct way to request an audio mode your receiving hardware can decode, reducing the temptation to solve a format mismatch with random OBS filters.

Compatibility check: J-Tech warns that unsupported Dolby Digital Plus or other higher audio formats may fail to appear on the optical or analog connectors. Set the console or HDMI source to PCM stereo when feeding the 3.5mm output. Optical is useful for a soundbar or receiver that explicitly accepts the chosen compressed 5.1 format; optical is not a general-purpose multichannel uncompressed PCM connection. Also note the documented incompatibilities with certain Apple TV and Comcast Xfinity devices: this is not a universal plug-and-play extractor for every streaming box.

Where it loses: 4K120 gaming passthrough is outside its documented capability, and ordinary output selection does not equal built-in 5.1 surround downmixing to two-channel analog. If your game screen must run at 4K120, compare the JTD-3200 or BK-21A instead. If you intentionally output encoded 5.1 sound and specifically need a stereo feed, use the JTD-3146’s documented downmix function. For a conventional 1080p60 stream with a 4K60 TV, the simpler JTD-322 remains the least confusing first purchase.

Insignia NS-HZ340: Best for buying locally and simplifying setup

Who it suits: creators who would rather collect a device from Best Buy and start a basic 4K60 console-to-TV audio setup than coordinate a specialty AV shipment. The NS-HZ340 is a distinct verified model number, not the similar-looking NS-HZ341. Best Buy lists an HDMI input and output, 4K60 HDR signal support, optical and 3.5mm audio outputs, and an audio mode selector for two-channel analog or supported 5.1 digital audio. It also specifies a supplied RCA-to-3.5mm adapter, while separate HDMI and audio cables are not included.

Why it earns a place: retailer-level availability is part of the buying decision, especially when a streamer needs a fix before an upcoming event. At the observed US store, Best Buy offered same-day pickup and shipping for the exact model. A clear audio mode selector is also useful for a nontechnical setup: two-channel stereo is the practical default when the receiving computer needs ordinary game sound, whereas optical surround is appropriate only if the downstream hardware explicitly accepts it.

Where it loses: like the JTD-322, this product does not preserve a 4K120 console output. It is also not an encoder, audio mixer or way to send game video into OBS by itself. If you already own a capture card whose HDMI audio reaches OBS cleanly, buying a second extraction box may add unnecessary complexity. If your need is eARC sound from a TV’s own apps, this basic source-path extractor is not the right reason to purchase the Insignia unit; compare a specifically documented ARC/eARC product instead.

Buying decision: choose the NS-HZ340 over JTD-322 if the convenience of immediate retail pickup, a straightforward return path and a familiar store outweigh the price difference. Choose JTD-322 if you prefer the detailed manufacturer descriptions of EDID modes and want the lower listed direct price. Neither should be sold to a 4K120 owner as a no-compromise gaming passthrough.

OREI BK-21A: Best when a console and streaming box share one display

Who it suits: a creator with two HDMI source devices—such as a console and a separate content player—who needs to select one device for a TV or monitor while still extracting sound to optical or analog equipment. OREI documents two HDMI inputs, one HDMI video output, separate optical and 3.5mm outputs, 48Gbps-class HDMI 2.1 bandwidth and manufacturer-listed support up to 4K120. Unlike OREI BK-21, the BK-21A includes the external audio extraction ports.

Why it is different: the BK-21A solves the source-count problem and the audio-routing problem together. An EDID DIP switch offers explicit audio mode presets. OREI’s instructions identify a two-channel PCM setting for the analog jack and a compatible 5.1 setting for optical equipment; this is more helpful than pretending that every codec can be carried through every port. For a PS5 and a gaming PC that are used at different times on the same display, one remote or front switch can simplify a crowded desk.

Critical streaming limitation: it is a source selector, not a seamless live-video switcher. OREI says the connected display normally blanks briefly as the HDMI handshake renegotiates when changing HDMI inputs. That makes it appropriate for choosing which device to play, but unsuitable as the only tool for polished instantaneous camera cuts in a broadcast. Its two inputs do not make a two-source composite or independent dual-display feed.

Availability and safety: the OREI direct storefront showed the model unavailable, while a US Best Buy listing offered the BK-21A for $49.99. Treat it as a seller-specific option, confirm final availability and avoid mixing up BK-21A with BK-21. Like other compliant HDMI hardware, it does not remove HDCP restrictions for a capture device. If you do not need to alternate between two HDMI sources, a single-input audio extractor is the cleaner and often cheaper solution.

J-Tech Digital JTD-3146: Best for a documented surround-to-stereo conversion

Who it suits: a streamer with a known 5.1-channel input that must become a two-channel analog feed, rather than merely moving an already-stereo signal from HDMI to an audio jack. The JTD-3146 / JTECH-EXD-ARC specifically advertises supported 5.1-to-stereo downmixing and provides RCA left/right output plus optical output. This is a narrower but important function: many ordinary extractors require the source itself to output PCM stereo and cannot decode or downmix the audio format you have selected.

Why the conversion matters: a stream input that receives unintelligible or silent encoded multichannel audio cannot be repaired simply by turning the OBS volume slider up. When a console, player or TV legitimately emits a supported 5.1 signal, the JTD-3146’s documented downmix behavior can produce a usable two-channel RCA feed for an analog audio interface. Its EDID selector helps the source and extractor negotiate an expected signal. The product also supports audio extraction from a compatible TV over HDMI ARC, but not eARC.

Do not overread the spec: J-Tech’s documentation describes downmix of supported standard 5.1 formats; it does not establish universal decoding of every Dolby Atmos, DTS:X or Dolby Digital Plus stream to stereo analog. It lists 4K60 HDMI 2.0b video passthrough. The manufacturer’s pages contain both a broad format table for HDMI passthrough and a narrower extraction/downmix description, so make your actual output-mode and codec choice conservatively. For OBS stereo, either use a supported downmix route or configure the source for PCM stereo before recording.

Trade-off: this model costs more than the two basic 4K60 extractors while offering no 4K120 video path. It makes sense when decoding/downmix is the specific obstacle. If the source already supplies PCM stereo, its extra conversion capability adds little. If 4K120 is nonnegotiable, choose a higher-bandwidth extractor and separately plan how to obtain stereo; do not assume an 8K label implies more audio-processing functions.

J-Tech Digital JTD-3200: Best premium 4K120 and television eARC audio

Who it suits: a higher-end gaming or production setup that needs a 4K120 video path alongside more varied audio destinations. The JTD-3200, marketed as JTECH-8KAE, is documented for up to 8K60 with particular chroma limits or 4K120 video. It accepts an HDMI source, has a video HDMI output and offers optical, analog and two function-specific HDMI audio connections for soundbar or amplifier use. Manufacturer and Best Buy listings agree on the model identity and the $129.99 US product price.

Why it stands out: TV ARC and eARC source routing can matter when the streamer uses a modern television, an AV receiver and a second audio device. The J-Tech interface names the HDMI soundbar and amplifier outputs separately; its documentation explicitly warns they must be connected to the matching kinds of devices. EDID DIP settings can help control negotiated audio capability. In a console-to-TV streaming setup, the device can preserve a modern video path without making the TV’s speakers or HDMI eARC connection the only accessible sound route.

What it does not solve: the manufacturer explicitly says the JTD-3200 does not downmix audio. An Atmos or multichannel setting on the HDMI source does not guarantee stereo on its L/R output. When feeding a stream PC line input, start with PCM 2-channel at the source. Optical supports only its documented formats, and using the HDMI soundbar or amplifier ports requires compatible downstream equipment. Just because the video circuit carries 4K120 does not establish the exact VRR, ALLM, HDR and chroma combination for every console/display chain; verify the target mode before purchase.

Buying decision: choose this over a basic 4K60 extractor when your actual game monitor runs 4K120 and the eARC/HDMI-audio outputs will be used. If your only need is stereo into OBS at 1080p or 4K60, the JTD-322 is more economical and creates fewer possible format mismatches. A second capture card or audio interface may still be required; the JTD-3200 is not a USB recording device.

J-Tech Digital JTD-3255: Best midrange 4K60 route for TV audio return

Who it suits: a creator using a 4K60 television who wants separate digital and analog audio connections and specifically needs TV ARC/eARC routing, without paying for 4K120 features. The JTD-3255 is sold under the JTECH-4KAE name and has optical, stereo RCA and a separate HDMI audio output. Its official information identifies support for audio returned from compatible ARC/eARC televisions as well as extraction from an external HDMI source.

Why choose it: the stereo RCA jacks are convenient for an audio interface with RCA or quarter-inch line inputs when connected using an appropriate cable, while optical can serve a digital receiver or interface. A TV-return-audio route addresses a problem a basic console-source extractor may not: when sound originates from the television’s internal app rather than the HDMI source feeding the extractor. Use the model’s documented return-audio input/output mode and make sure the television is configured to send sound by ARC/eARC.

Trade-offs and status: the video side stops at 4K60. It is not the right unit for a 4K120 console-to-TV link. The J-Tech direct product page explicitly showed sold out, whereas Best Buy presented a $65.99 purchasable listing. This is a real stock discrepancy by seller, not a reason to label the device universally in stock. Confirm that Best Buy still accepts an order to your location. If you do not need TV return audio, choose the less-expensive JTD-322; if you need 4K120 plus eARC, compare the JTD-3200.

Buying guide: Avoid the audio problems that disrupt a stream

Understand the three connections, not just the box name

An HDMI audio extractor takes one source’s HDMI audio/video input, provides a continuing video output, and makes audio accessible from a separate port. That is different from a capture card, which ingests a video signal into a PC through USB or PCIe, and from an HDMI splitter, which may duplicate video without providing an accessible stereo audio output. A basic TV ARC/eARC converter also serves a different direction of audio flow. Match the product’s labeled input and output connectors to the direction sound must travel: console to TV plus stream PC, or TV internal app to an external receiver or interface.

Make a small cable map before ordering. For a typical console stream, draw console HDMI → extractor HDMI input → extractor HDMI output → capture device or display, then add an optical or analog audio line from the extractor to the appropriate receiving gear. But inserting an extractor before a capture card is not always advisable: it adds another device negotiating HDMI EDID and HDCP state. If the capture card already receives usable sound, leave the HDMI chain alone and capture that audio directly instead of duplicating it unnecessarily.

Optical, 3.5mm and RCA are not interchangeable audio formats

A 3.5mm or left/right RCA output is normally an analog stereo signal. It is the simplest route for an ordinary line-level recording input, assuming the sound device has the correct line-in connector. An optical S/PDIF connection carries digital audio; you need a real optical receiver, compatible USB digital interface or a separately chosen converter. The computer’s standard 3.5mm microphone socket cannot decode an optical cable, and a passive adapter cannot convert digital optical into analog sound.

Optical connections also have format limits. Standard S/PDIF is suitable for stereo PCM and certain compressed surround formats, but it does not become a universal eight-channel uncompressed PCM or lossless HDMI audio link. HDMI passthrough can support audio formats that the same box cannot output via analog or optical. Read the format list for the specific output port, not just the broad “Dolby Atmos” logo at the top of a product page. If an OBS input requires stereo, choose stereo at the source or buy a model whose downmix behavior is clearly documented.

Do not sacrifice the video mode your gaming screen uses

A 4K60 extractor can be perfectly adequate for a 1080p60 stream, but that says nothing about whether it can sit between a 4K120 console and a 120Hz television. If your gameplay display uses 4K120, select a product with the actual supported 4K120 passthrough and check the exact color format, HDR state, cable rating and any display feature you use. HDMI 2.1 is not, by itself, proof of every possible combination of VRR, ALLM, deep color and 4K120. The two 4K120 options in this comparison solve different problems: BK-21A switches between two HDMI sources; JTD-3200 emphasizes more advanced audio destinations and eARC.

As a practical diagnostic, temporarily bypass the extractor if your TV stops offering 120Hz or HDR. If the console and TV work directly but not through the inserted box, examine the model’s video ceiling, EDID selection, HDMI cable lengths and display input configuration. Do not lower a competitive player’s monitor refresh rate merely because the streaming computer’s recording is only 60 frames per second. The display path and broadcast output have separate requirements.

EDID negotiation controls whether the correct audio appears

EDID is the set of display/audio capabilities the HDMI source believes are available. Many extractors offer 2CH or 5CH modes because a source may otherwise advertise a surround format the 3.5mm analog jack cannot decode. When feeding ordinary stereo into OBS, configure the source to PCM stereo and use the appropriate 2CH preset on the extractor. When feeding an optical receiver that supports standard Dolby Digital 5.1, the documented 5CH preset can be a better match. Leave a display-following EDID setting in place only if you have confirmed it yields an audio format every downstream device can use.

For consoles and gaming PCs, change the audio source format before adding software filters. If the interface shows an active input but OBS records silence, verify whether the source is emitting PCM or a compressed format; then confirm the extractor’s physical switch and the audio interface’s input type. A software gain filter cannot repair the wrong digital codec or a disconnected physical input. If you must combine game audio with a microphone, do that intentionally on the streaming PC or audio mixer after establishing one clean game-audio feed.

Separate source audio, TV eARC audio and stream monitoring

A unit can be branded “eARC extractor” yet provide several different routing functions. Source extraction means sound is taken from an HDMI console, PC or player connected to its HDMI input. TV ARC/eARC extraction means sound is returned from the TV, potentially including the TV’s built-in apps, over a designated HDMI ARC/eARC connection. Some models support one direction only or restrict which ports work in return-audio mode. For example, J-Tech’s JTD-302 information specifically limits TV ARC extraction to optical, and the JTD-3200 has designated HDMI audio output functions.

For streaming, decide which audio you actually need in OBS and which audio should play in your headphones. If the television and streaming PC both monitor the same HDMI source at slightly different delays, you may hear an echo. Turn off unnecessary TV speaker monitoring or route headphones through a single intentional monitoring device. If OBS also captures the same game audio through a capture card, disable one duplicate path. Removing duplicate sources is generally more reliable than trying to time-align two unnecessarily different routes.

Price the full signal chain and verify stock by seller

The extractor is only one part of the expense. You may also need a correctly rated HDMI cable, an optical cable, a genuine digital-to-analog converter, a USB audio interface with proper line inputs, or a stereo cable with matching plug types. If the $34.99 JTD-322 solves a simple PCM stereo problem, a premium eARC box will not automatically improve the OBS sound. Conversely, a low-priced 4K60 unit becomes a false economy if it prevents the television from receiving the 4K120 signal that the gamer actually uses.

Retailer status can disagree across sites and across days. The OREI BK-21A was orderable in a Best Buy listing but marked unavailable on the OREI page, while the JTD-3255 showed the opposite seller-state problem: sold out at J-Tech and available to order via Best Buy. Do not substitute a similar name or a different version just because a search result looks cheaper. Verify the SKU, shipping destination, price, return policy and the source/display connectors in the cart. The table reports observations from October 30, 2026, not a guarantee of continuing availability.

How to connect an HDMI audio extractor to OBS without double sound

Option A: The extractor provides a separate analog stereo line feed

1. Start with the HDMI source and capture/display directly connected and confirm that video works in the target mode. This establishes a baseline before inserting additional hardware.
2. Power off the relevant equipment or follow the hardware manuals’ safe connection procedure. Connect the source HDMI output to the extractor’s HDMI input and the extractor’s HDMI video output to the next supported device in the chain. Confirm the extractor has its required power supply.
3. Configure the console or PC HDMI audio output for two-channel PCM. On an extractor with an EDID switch, choose its documented stereo/2CH setting. Use the box’s 3.5mm or RCA analog output, not its optical port, for an analog interface.
4. Connect the analog output to a line-level input on the streaming PC or audio interface using the correct stereo cable. Do not assume a headset-combo jack or microphone input is a suitable unattenuated stereo line input.
5. Open OBS Studio on the stream computer. In Settings > Audio, select the appropriate input under a Mic/Auxiliary Audio device slot, or add an Audio Input Capture source to the required scene and choose the interface input. Avoid configuring both routes for the same device.
6. Play game audio and watch the OBS meter. Record a short sample locally. Check stereo balance, distortion, clipping, audio delay and whether removing or muting the HDMI audio source from the capture card eliminates duplicates.

Unlike a USB HDMI capture device, the extractor itself is not expected to appear as a selectable audio device in OBS. OBS sees the sound card or USB interface receiving the analog feed. If the interface only has a mono microphone input, use a proper stereo interface rather than treating one jack as a stereo recorder. A pad or level adjustment may be necessary if your input is designed for mic sensitivity rather than a line signal.

Option B: Keep game audio embedded in HDMI through the capture card

1. Connect your source to the capture card using the manufacturer’s supported HDMI wiring and connect the capture card to the streaming PC.
2. Open OBS and add the appropriate Video Capture Device source, selecting the correct capture hardware.
3. Confirm that the capture device’s audio is present using its documented audio mode or capture-source configuration. Device audio configuration varies by capture-card model and software version.
4. Record a test that includes gameplay, microphone and stream alerts. If game audio is already present once at the right level, do not add an unnecessary external audio extractor.

This route is usually preferable when the capture card already handles audio correctly. Audio extraction is a problem-solving accessory, not a mandatory part of the standard HDMI game-capture chain. Add it only to supply a separate monitor/soundbar path, resolve an actual output-format limitation, or send audio to equipment the capture card does not serve.

Option C: Route optical audio into a digital audio interface

1. Confirm your interface has an actual S/PDIF optical input and supports the selected audio format. An optical output on the interface is not an input.
2. Connect the extractor’s optical output to the interface’s optical input and choose PCM stereo on the HDMI source unless the interface is explicitly designed to decode the surround bitstream being transmitted.
3. Configure the interface’s digital input, sample-rate and clocking according to its manufacturer instructions. Then choose the interface in OBS and record a synchronization test.

If the interface has no optical input, do not buy a cheap passive optical-to-3.5mm adapter: optical is digital and analog stereo needs active conversion. Even with the correct hardware, an optical connection is not automatically better sound than a clean analog line feed. Choose the route your actual receiver accepts.

Troubleshooting: Fix silence, echoes and missing 120Hz modes

HDCP is not an extractor feature you can assume away. Elgato states that its capture devices cannot record HDCP-protected HDMI signals. With a PlayStation 5, its official setup documents show a legitimate system setting to disable HDCP for supported gameplay capture, but protected streaming and entertainment apps are not made capturable by that action. An audio extractor described as HDCP 2.3 compliant is not a device for bypassing content protection.

If signal negotiation fails, work from the simplest chain outward. Connect the HDMI source directly to the display, verify audio and video, add the capture card if present, then insert the extractor. Change one variable at a time: source PCM mode, extractor EDID, cable and output device. Only after the sound reaches the expected recording input should you attempt fine OBS filters or sync adjustments. Never treat volume gain as a fix for a missing hardware signal or the wrong audio codec.

Frequently asked questions

Do HDMI audio extractors work with OBS Studio?

Yes, indirectly. An extractor can provide analog stereo to a sound interface or optical S/PDIF to a compatible digital interface; OBS records from that receiving interface. The extractor alone generally does not show up as an OBS USB capture source. Alternatively, a capture card can bring HDMI audio into OBS without external extraction. Verify which specific device the stream PC sees before choosing any filters.

Do I need an HDMI audio extractor with an Elgato capture card?

Not if the capture card already carries your desired game audio cleanly into the streaming PC. You may benefit from an extractor when you need a separate line output for a mixer, legacy speakers or specialized audio routing. First test the capture card’s built-in HDMI audio. Adding hardware without a clear purpose can create an extra HDMI handshake and duplicate monitoring paths.

Can an optical HDMI extractor provide audio straight to my laptop?

Only if the laptop or connected audio interface provides a compatible optical S/PDIF input. A normal 3.5mm headset or microphone port is not an optical input, and a laptop’s HDMI output is not typically an HDMI recording input. For straightforward laptop streaming, choose a USB audio interface with a proper analog line input and an extractor providing PCM stereo, or record the audio embedded in a supported USB capture card.

Will an HDMI audio extractor preserve 4K120 and VRR?

Only where the exact model, source, cable and display support the desired signal combination. J-Tech JTD-3200 and OREI BK-21A have manufacturer-listed 4K120 video passthrough, while the basic JTD-322 and Insignia NS-HZ340 are 4K60 products. Do not infer full VRR support for an arbitrary extractor from the words HDMI 2.1 alone; review the manufacturer’s model-specific feature list and try your target display mode before a live event.

Which extractor converts surround audio into stereo?

The J-Tech Digital JTD-3146 explicitly documents downmixing supported standard 5.1 sound to stereo RCA. Many other devices simply extract a codec that must already be compatible with their outputs; some pass more formats over HDMI than their optical or analog jacks can decode. If your source can emit PCM stereo, selecting that format is often the simplest OBS solution and does not require surround downmix hardware.

Is ARC the same as eARC for a streaming audio setup?

No. Both are return-audio paths between a TV and compatible connected equipment, but their supported capabilities and the extractor’s actual output routing can differ. If the sound originates from a console attached to the extractor’s HDMI input, ordinary source extraction may be sufficient. If the sound originates inside the TV’s apps, you need a model that explicitly supports TV return audio and the correct ARC/eARC cable/port arrangement. The JTD-3146 supports ARC but not eARC; the JTD-3200 supports both.

Can an extractor bypass HDCP so I can stream protected video?

No. HDCP compliance does not grant recording access to protected video. Capture cards typically reject protected HDMI output. Follow your capture device’s official gameplay setup and the streaming service’s rights and restrictions rather than attempting to use an audio extractor as a bypass. Elgato documents a PS5 gameplay setup that turns off HDCP, but that does not authorize or enable capture of protected media apps.

Which extractor should a beginner buy first?

Start by checking whether OBS already receives the game sound from your capture card. If it does, buy nothing. If you need a clean analog stereo feed and your display runs at 4K60 or below, compare the JTD-322 and the retail-available NS-HZ340. If you must retain a 4K120 display route, plan around the BK-21A or JTD-3200 and confirm which extra functions you need. If your actual issue is decoding 5.1 audio to stereo, choose a documented downmix unit rather than paying for unused 8K video capability.

Final thoughts

For a typical console-to-OBS workflow with a 4K60 display, J-Tech Digital JTD-322 is the most practical first comparison because it gives you an identifiable HDMI source path, 3.5mm stereo, optical output and explicit audio EDID choices at a modest US listed price. The Insignia NS-HZ340 offers a convenient Best Buy purchasing route. Choose OREI BK-21A when the bigger problem is selecting between two HDMI sources, and J-Tech JTD-3146 when a real 5.1-to-stereo downmix is required. For a higher-bandwidth 4K120 TV and multiple audio destinations, examine JTD-3200; for 4K60 TV return audio with a lower budget, verify whether JTD-3255 is currently available from your preferred seller. Before paying, check your screen’s actual video mode, the source audio format and the receiving OBS interface. If the existing capture card already supplies clean sound, skip the extractor entirely.
