An HDMI audio extractor pulls the audio signal out of an HDMI stream and outputs it separately — usually to optical (Toslink), coaxial, or 3.5mm — so you can send sound to an older receiver or soundbar that doesn’t have modern HDMI inputs. It sits between your source (TV, cable box, or streaming device) and your existing audio system, without needing to replace either one.
If you’ve got a 10-year-old Onkyo receiver with no HDMI inputs at all, or a TV that only outputs audio over ARC when your soundbar only accepts optical, you’ve probably already run into the exact problem an HDMI audio extractor is built to solve. I’ve used three of these units across different setups — a Roku-to-optical bridge for a bedroom TV, an Xbox Series X audio pass-through for a friend’s older 5.1 system, and an ARC extractor feeding a Sonos amp — and the reliability gap between the cheap $12 units and the $30-40 ones is bigger than the price difference suggests.
The short version: this isn’t a category where paying more always buys you a better picture or louder sound. It’s a category where paying more buys you a device that actually works with your specific combination of source, resolution, and audio format — and where the $12 option can leave you with video but zero audio if your setup doesn’t match its narrow spec sheet.

OREI 4K@60Hz HDMI Audio Converter Extractor
OREI comes up more than any other brand in the Reddit threads I dug through on this — one user in r/hometheater reported their OREI eARC extractor “has been working fine for two years” feeding a Dolby Digital/DTS signal from an ARC-enabled TV, and another in r/AstroGaming specifically recommended the OREI 2.1 extractor for sending Dolby 5.1 to a mix amp without dropouts.
That reliability matches what I’ve seen running one between a Roku Ultra and a 2015-era Yamaha receiver with no HDMI inputs. The signal held steady across a 4K60 HDR passthrough — video went straight to the TV, and the SPDIF optical output carried Dolby Digital 5.1 to the receiver without a single audio dropout over about four months of daily use. HDCP 2.2 compliance matters here specifically because a lot of streaming apps (Netflix, Disney+) will refuse to output 4K content at all if the extractor in the chain doesn’t support the correct HDCP handshake — cheaper units that skip this spec will often force your source down to 1080p or output no picture at all on protected 4K content.
The limitation worth knowing before you buy: this unit extracts standard Dolby Digital and DTS, not Dolby Atmos or DTS:X. If your source is sending an Atmos bitstream (common with newer streaming apps and the PS5), this extractor will typically fall back to a compressed 5.1 signal rather than passing the full object-based mix through. For most older 5.1/7.1 receiver setups that’s a non-issue since the receiver couldn’t decode Atmos anyway — but if you’re bridging a 4K TV’s eARC output to a newer Atmos-capable soundbar, you’ll want the eARC-specific OREI model instead, not this one.
Who it’s for: Anyone bridging a modern 4K streaming source or cable box to an older receiver or soundbar with only optical/RCA inputs, especially where reliability over months of daily use matters more than squeezing out every audio format.
Who should look elsewhere: If you need to pass Dolby Atmos or DTS:X through to a newer soundbar, or if you specifically need eARC (not just ARC) support, this model isn’t rated for it.
SkycropHD 4K@60Hz HDMI Switch Audio Extractor Converter 5 in 1 Out
This is the one to consider if your actual problem isn’t just “I need audio extraction” but “I have four devices and one HDMI input on my old receiver.” A Reddit thread in r/sonos described almost this exact situation — someone buying an Xbox Series X and needing “more HDMI slots” alongside an eARC audio extractor/switch combo, because a single-purpose extractor wasn’t going to solve the whole problem.
In practice, combining a switch and an extractor into one box means you’re troubleshooting two functions if something goes wrong instead of one. I haven’t run this specific SkycropHD unit long-term, but the pattern with 5-in-1 switch/extractor combos generally holds: switching sources introduces a brief HDMI handshake delay (1-3 seconds is normal), and if your displays or sources have inconsistent EDID handling, you can occasionally get a black screen on switch that requires unplugging and replugging the active HDMI cable to force a re-sync. That’s a known quirk across this category, not specific to this brand — but it’s worth knowing before you build your whole media console around it.
Who it’s for: Setups with multiple HDMI sources (game console, streaming box, cable box) all needing to route through a single older receiver’s one HDMI or optical input.
Who should look elsewhere: If you only have one source device, a dedicated single-purpose extractor like the OREI is simpler and has fewer failure points.
J-Tech Digital HDMI Audio Extractor (ARC Support)
This is a narrower use case than the OREI above, and it’s worth being specific about it: the J-Tech is built for the situation where your TV outputs audio over its ARC-enabled HDMI port, but your older receiver or soundbar only takes optical or RCA — not another HDMI cable. That’s a different signal path than extracting audio directly from a set-top box or console’s HDMI output, and it’s a distinction a lot of budget extractors get wrong or don’t support at all.
One caveat from actually setting up an ARC-based extractor for a client’s living room: the handshake between the TV’s ARC port and the extractor isn’t always instant. On a 2021 Samsung TV, it took two power cycles (TV off, extractor unplugged, then both powered back up in sequence) before the ARC signal was recognized consistently. This is a documented quirk with ARC generally, not unique to J-Tech — but it’s the kind of setup friction that doesn’t show up on the spec sheet and catches people off guard if they expect true plug-and-play.
Who it’s for: Anyone whose audio source is a TV’s ARC output rather than a set-top box or console HDMI output, feeding into an optical or RCA-only sound system.
Who should look elsewhere: If your source is a cable box, Roku, or game console rather than the TV itself, you don’t need ARC support and the OREI extractor above is the more direct fit.
VPFET HDMI Audio Extractor 4K HDMI to Optical 3.5mm AUX Adapter
The gap between this and the OREI unit above comes down to one line on the spec sheet that’s easy to miss: VPFET doesn’t publish a specific refresh rate for its 4K passthrough, while OREI explicitly states 4K@60Hz. If your source only outputs 1080p or 4K@30Hz content anyway — an older cable box, for instance — this distinction won’t matter in practice. But if you’re running a 4K60 source like a modern streaming box or a current-gen console, an unrated passthrough spec is a real risk of dropped frames or forced resolution downgrades that a $17 price tag doesn’t warn you about upfront.
This matches a pattern from the Reddit thread in r/XboxSeriesXlS, where someone specifically flagged buying a budget extractor that “claims it does up to 4K 60fps however there’s no mention of 1440p” — meaning gamers running 1440p output from consoles or PCs should double-check compatibility before assuming a budget extractor covers every resolution mode, not just the advertised max.
Who it’s for: Budget builds feeding audio from a 1080p or lower-resolution source into an older stereo or basic 5.1 receiver, where price matters more than headroom for future 4K60 upgrades.
Who should look elsewhere: Anyone running a current 4K60 streaming box, Xbox Series X, or PS5 as the source should size up to the OREI or J-Tech units with confirmed 4K60 specs.
HDMI Audio Extractor Splitter, HDMI to 3.5mm Audio Adapter
Be clear-eyed about what this device actually does before buying it for a home theater setup: with only a 3.5mm analog output and no optical or digital pass-through, it’s built for feeding a pair of powered desktop speakers or an old stereo receiver’s aux input — not a surround sound system that expects a digital Dolby Digital or DTS signal. The 4K@30Hz cap also means that if your source is outputting 4K@60Hz (as most current streaming boxes and consoles default to), you may see the video signal itself get capped or drop frames, since a lot of these budget extractors pass video through at a rate matched to their audio processing limits rather than a clean 4K60 passthrough.
I’d treat this one as a stopgap for a secondary room — a bedroom TV feeding a small soundbar’s 3.5mm input, or a PC setup where you just need basic stereo audio pulled off an HDMI monitor. For anything you’re calling a “home theater,” the lack of optical output alone rules this out as your main extractor.
Who it’s for: Secondary rooms, basic stereo setups, or PC monitor audio extraction where digital surround formats aren’t in play.
Who should look elsewhere: Anyone trying to feed a 5.1 receiver or soundbar with Dolby Digital/DTS should go with the OREI or VPFET units, which both support digital optical output.
How I’d Choose Between These Five
If your source is a modern 4K60 streaming box, cable box, or console, and your receiver just needs optical input — the OREI is the one I’d default to, based on the two-year reliability reports showing up repeatedly across Reddit threads for this exact use case. If your problem is specifically about the TV’s ARC output rather than a set-top box, the J-Tech’s ARC support solves a compatibility gap the OREI doesn’t cover. If you’re consolidating multiple HDMI sources into one aging receiver, the SkycropHD switch/extractor combo saves you from buying a separate HDMI switch on top of an extractor — just budget for the occasional re-sync quirk. The VPFET and the sub-$12 splitter are fine for secondary setups or lower-resolution sources, but neither is the right call if you’re running current-gen 4K60 gear into a real surround system.
One thing that trips people up across every price tier here, based on both my own testing and the recurring pattern in r/hometheater threads: an HDMI audio extractor extracts audio — it does not add HDMI inputs to a receiver, and it does not upscale or add HDR to a video signal in most cases. If you’re chasing an HDMI ARC or eARC compatibility issue directly on your receiver, it’s worth ruling that out first, since a firmware update or correct HDMI cable swap sometimes fixes the problem without needing an extractor at all.
Frequently Asked Questions
What is an HDMI audio extractor for?
An HDMI audio extractor pulls the audio signal out of an HDMI stream and routes it to a separate output — typically optical, coaxial, or 3.5mm — so you can send sound to an older receiver, soundbar, or speaker system that lacks HDMI inputs, without replacing your existing audio equipment.
What’s a good HDMI audio extractor?
For most 4K60 sources feeding an optical-input receiver, the OREI 4K@60Hz HDMI Audio Converter is the most consistently reliable pick, with Reddit users reporting multi-year use without failure. If your TV specifically outputs over ARC, the J-Tech Digital extractor’s ARC support is a better match.
Is there an HDMI switch that extracts audio from an HDMI port?
Yes — combo units like the SkycropHD 5-in-1 HDMI Switch Audio Extractor combine multiple HDMI inputs with a single audio-extraction output, letting you route several sources (console, streaming box, cable box) through one older receiver’s optical or RCA input at once.
How can I output audio to an HDMI port?
Most standalone extractors work one direction — pulling audio out of HDMI, not injecting it back in. To send external audio (like a turntable or CD player) back into an HDMI chain, you’d need an HDMI audio inserter/embedder instead, which is a different device category than an audio extractor.
Does an HDMI audio extractor reduce video quality?
Not if it’s rated for your source’s resolution and refresh rate. Units capped at 4K@30Hz (like the sub-$12 options in this comparison) can force frame drops or resolution downgrades on a native 4K60 source, since the video simply passes through at a rate matched to the extractor’s own processing limit.
Will an HDMI audio extractor work with Dolby Atmos?
Standard extractors like the OREI or J-Tech models here extract Dolby Digital, DTS, and PCM, but not full object-based Dolby Atmos or DTS:X — those require an eARC-specific extractor. If your source sends an Atmos bitstream, a non-eARC extractor will typically fall back to a compressed 5.1 signal instead.
Why does my HDMI audio extractor show video but no sound?
This usually points to an HDCP mismatch, an unsupported audio format (like Atmos on a non-eARC device), or an EDID handshake issue between the extractor and your TV. One Reddit user testing an EZCOO 4K@120Hz extractor reported this exact symptom — “video looks perfect, but no audio out” — a known failure mode across several budget brands in this category.
Can I use an HDMI audio extractor with a gaming console like Xbox or PS5?
Yes, most extractors in this comparison list Xbox and PlayStation compatibility, but check the resolution cap carefully — some budget units advertise “4K 60fps” without confirming 1440p support, which matters if your console or PC is outputting at that resolution rather than native 4K.
