This handy little device extracts the audio component of an HDMI signal, and makes it available via either analog stereo output on a 3.5mm stereo jack, or digital optical output via a TOSLink cable. No output cables are supplied, so you’ll have to make sure you have those.The first positive sign while setting this up was that the brand name on the box matched the brand name on the device itself. (And while it’s not at all a famous brand name, it is at least pronounceable!)The second positive sign was that it came with a long-ish USB power supply cable, which is not necessarily the norm these days. No power adapter is supplied, so again, you’ll have to make sure you have one available.I tested this device with a Roku Express streaming box, and the it worked well. Installing it is straightforward. To connect it, you plug the HDMI cable from the Roku box into the device, then run a second HDMI cable from the device to your TV. And yes, that second HDMI cable is not supplied, so you’ll have to have one available!The video is viewable while the sound outputs are being recorded. But it’s not mandatory that you connect that second HDMI cable, so you can just record the sound without viewing the video.Once it’s connected to the HDMI input, the audio component of that signal available at two outputs on the device. One is a 3.5mm stereo “mini” jack, like for headphones. The second is a digital optical output for a TOSLink cable. And you’ll have to make sure you have the appropriate cables for the output(s) you want to use.I tested the analog output by recording it on a Zoom H1 recorder, then playing back the recording on my desktop computer’s pretty good speakers & subwoofer. The sound was clear and undistorted, and I there was no audible “muffling” or other changes to the audio quality.I tested the digital output by connecting it to the AV receiver that’s normally connected directly to the TV. The sound was indistinguishable from what I normally experience, which means it was good.I also checked two other things: first, are both outputs are available at the same time? They are. Second, is there any “lag” in the sound output when viewing the video through this device? When I ran digital optical output directly into the AV receiver, there was no visible lag in the sound.So overall, this is a well-built, solid little device that does its one job very well. And based on some comparison shopping, is a good value. If you have a need or desire to record the sound part of an HDMI signal, I would highly recommend this device.

Works excellent! I use it with my windows 11 PC to hook it up directly to an older surround sound receiver. The boost in sound quality was immediately noticeable. You can't put a price/value on premium sound, but this device is worth every penny.

EAsy to use audio extractor to send audio to older AV equipment.This was drop-in for me. I had a different (2 channel only) HDMI extractor in place behind my projector. I'm sending the signal to an old surround sound receiver that predates HDMI. I added speakers (finally) to this setup for 5.1 and realized the existing extractor was only 2.0. No brainer replacement with this device for $20 (at time of review). Even buying two extractors has been cheaper than replacing the AV receiver!Some caveats of this extractor, it doesn't do 4K@60hz, only 30. My TV does 4K@60hz, but none of my current equipment does. I'm actually using with my projector which is 1080p. So this caveat doesn't affect me now, but might later., There's some other issues with how it does EDID 'handling and signal passing. If you've got old HDMI devices or 720p devices, you might need to fidget with the signals. The aux output is 2.0 channels, the optical is 5.1. Don't try and pass through 7.1, and you can't use analog cables to get surround. Since those issues shouldn't affect most people, don't worry, this thing works fine.

If you're just trying to capture the PCM stream from the HDMI interface, this does the job nicely. Utilizing Type-C for power is convenient, as most A/V receivers nowadays have a couple of USB ports that can provide enough power for this interface.Deducting 2 stars, only because once this interface was in line between my media player (tested both on AppleTV latest gen and latest gen nVidia Shield). When this is in line, it will not pass through HDR / Dolby Vision. I confirmed this is not a HDMI cabling issue by swapping with other HDMI 2.1 compliant cables. Other than that, whatever stream you choose as your HDMI audio output will be the channel form that comes out of the optical output (either 2.0 or 5.1 tested for me).

Works great with my projector in the bedroom. I needed to be able to use the headphone jack on the projector to power my speakers but I wanted a way to set up Bluetooth headphones without worrying about the volume settings. This give me a direct path to the sound to connect my Bluetooth adapter and still use the remote control to must the speakers when my wife is in bed asleep. Simple to set up and hide out of the way.
