HDMI Audio Extractor, 4K HDMI to Optical SPDIF + 3.5mm Stereo + RCA L/R Audio Adapter Converter with Volume Control Support 4K@60Hz HDCP 2.2 HDR 3D YUV 4:4:4

This Extractor is exactly what I needed to solve my audio issues. My older tv does not have digital audio output to go to my Yamaha head unit. This extractor not only solved that issue, but even within the digital audio issue, it solved a second, unexpected issue as well. Some apps on my AppleTV use a different digital audio signal and it drops some audio in 5.1. This extractor has both a digital optical audio Out, as well as a 2.1 Stereo Output that I also connected to my Head unit. With one flick of the selector switch on this unit and I can toggle between 5.1 or 2.1 stereo to fix the dropped audio issue with the certain Apps. (So far only the main ESPN broadcast and South Park, have had this issue for me, but I’ve read now other Apps and units like Firestick etc., may experience similar issues with sound bars or other audio devices). This extractor solved two issues I didn’t even know I had. With a little tinkering and experimentation I was able to dial this unit in and unlock the great surround-sound that my older TV wasn’t able to do. Highly recommended for similar issues.

Does the job. I'm using it to capture audio from a portable bluray player and listen to movies through headphones. It zeros any noise interference I was having before when I would plug into the player directly. Works perfectly. The volume knob is convenient too.

Exactly what we needed to make our audio work better!

This device works as advertised, in that it does pull the audio from an HDMI signal, and convert it into analog audio through RCA jacks, which is how I'm using it. However, the level of noise coming from the device when there's no input audio signal is frankly impressive, plus it occasionally drops audio when the levels go too low. Think of the hissing noise from a cheap LP after all the tracks have played, but before you pull the stylus off the record, except it's very digital sounding. It's just cheaply made, and although it works, I'm looking for an alternative that doesn't sound like I've left a radio tuned to static in the background. Update: Tried playing discs with 5.1 and 7.1 audio tracks on them, and it's routing rear speaker signals to the two outputs. Any 5.1 or 7.1 (or presumably anything more complicated than 2 channel audio) signal renders this thing absolutely useless. While it is amusing to watch movies with zero dialogue and occasional sound effects for a minute or two, it gets old quickly. This is a surprising limitation, but drops it from 3 stars to 1 for me.

It's a really great product however it didn't solve my specific problem but the product works really well otherwise.

This is a great little piece of kit. It does exactly what it says it should do. It extracts audio from HDMI signal cable. I've used it on several gigs to pull high quality sound to feed a PA system. If you need this kind of tool, this one is a performer. I will say that don't expect it to handle a loss of HDMI signalling and then a reapplication of the signalling. The unit need to be recycled to detect the audio traffic. There is a convenient led indicator to let you know if audio signalling is present on each HDMI interface. Right now I have it pulling audio from a mini-MAC HDMI interface to feed it to a 5.1 sound system. Works great! You wont be disappointed.

There are many hdmi decoders, but this one is the only unit I found that provides full spectrum hdmi passthrough, an optical outlet, RCA outputs and a headphone jack with a level control. I also has 4 indicators for HD, HDMI, etc. Housed in a cast aluminum case, with excellent instructions with full specs., this is much more like the professional electronic equipment that I have worked with than a consumer product. It's 90dn noise floor and .1% distortion are honest numbers that I believe it meets. You need a usb charger, but the unit is cheap for all you get and works great!

It does do its job, but after about 2 weeks of use, every time you touch it or adjust the volume knob, it makes a loud pop/hiss and disconnects for a few seconds. It also has a fair amount of background noise/hum--it's not super noticeable right now for me, but if it gets worse as indicated by some other reviews, it would make this pretty unusable.

Great extractor with a volume knob (not many have this). Works as described.

I’ve had two Xbox series X’s and two controllers, even headphones; and always I hear crackling when I have wired headphones connected to a controller. Somewhere in my house is interference, and this device solves those issues. Instead just plug your headphones in and use the dedicated volume knob to adjust the volume. No need to touch the tv’s volume, the tv could be at zero volume.

Did not work going from TV hdmi earc to extractor to amp. Optical also did not work.

Works great for my needed purpose. My monitor doesn't have speakers so my passthrough capture card wouldn't get any audio. This device allowed me to select HDMI as an audio output device. The included volume knob is nice to have, as i've connected a pair of monitor headphones so I can ensure my captured audio matches source output. Highly recommend

I had a multi-port switcher from amazon, a non-branded unit that accepted 4 HDMI sources and performed audio extraction but clearly EDID didn't work on it as my firestick kept throwing PCM audio instead of DTS. I figured I'd try one of these to see if it solved the issue and it works PERFECTLY. My surround sound system is also old but I like it! It's a Logitech z-5500. Now I can enjoy movies and TV shows with true 5.1 instead of whatever garbage PCM creates!! Excellent purchase and I will likely buy one more so I can use it with my xbox :)
