Tendak 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.

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!

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.

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.

Excellent product...I had similar device previously that was not nearly as good as this...this unit causes no RF interference and the volume control really lets you send a loud, clean signal.

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.

Works great! Works with Linux! The volume on the audio extractors built into monitors are very quiet. This gives a full, line-out volume. Great for hooking a computer to a stereo system.
