It works well
I'm normally hesitant to buy this sort small-brand Chinese hardware that floods Amazon, but there were no well known brands offering this part so I gave it a try. Happily I have had no issues. The option to use optical, 3.5mm, or hdmi pass through is very nice. I have not noticed any timing or latency with the audio matching up with the video. I took the enclosure off mine because I will be putting it inside a different system. the board is compact and clean.

Works, but doesn't support CEC
This works as described, but it doesn't support CEC. I used this to combine my AppleTV with a Karaoke system and although it replaces the audio properly, I lost CEC functionality between my AppleTV and my TV/Audio system. CEC support is important to me and the description says it supports CEC. The little booklet (manual) that came with the device doesn't say it supports CEC, so the Amazon description is misleading.

Works excellently.
For the venue I work at, we wanted to send video from a camera, and audio from the sound console, to a video monitor in the green room. For this purpose this product has worked excellently for several months now.

Supports 4k with stereo audio
This supports 4k video with stereo inserted audio. BUT, make sure you plug it into something that provides enough power. I didn't realize the brick I plugged into was only a 10w supply and it couldn't do 4k on that. Read the instructions and make sure you do it right. I had some issues with the mono price inserter because even after getting it replaced it only supported single channel audio, this solves that problem, very happy with it. I will update it if I have any issues

Works perfect
My computer graphics card does not output an audio signal on the HDMI output, so I had to find some way to combine audio and HDMI video. This did the trick!

The HDMI Audio Extractor is a great device. It worked perfectly for me. I used it to separate the audio from my PS4 and connect it to my surround sound system without any problems. It was really easy to use and set up. It comes with an HDMI to Optical Audio Adapter & 3.5 Audio Out Jack. I was able to enjoy high-quality audio on my surround sound system. The 3.5mm L/R Stereo Audio option was my choice for connection, and it provided crisp audio to the surround sound.

I ordered this HDMI audio extractor to connect my PS4 to my old sound system that only has optical and analog inputs. It works very well and delivers clear and crisp sound. The extractor supports 4K x 2K@30Hz resolution and 3D video, and it can extract audio from HDMI sources without any loss of quality. It has a switch that allows me to choose between optical and stereo output, and it also has an indicator light that shows the working status. It is easy to install and use, and it comes with a USB power cable and a user manual.

My fancy gaming laptop just can't output HDMI audio when connecting to a TV via HDMI. This device solves the problem; good thing I also had an extra HDMI cable, an extra 3.5 mm audio cable, an extra micro USB cable, and a free USB port for power. Now I can play all the fancy games my fancy gaming laptop allows for on the biggest display in my room.

I have a TV with separate old speaker system and no sound pass through, this worked precisely as advertised, easy to connect and use, sounds good and slight lag, affordable price to re-purpose your old stereo!
