Great Value for HDMI Audio Extraction
ecently bought this HDMI Audio Extractor for my home theater setup, and it’s been a solid addition to my media system. I needed a device to separate audio from my HDMI signal so I could send it to my soundbar via optical or 3.5mm audio without sacrificing video quality. This device does the job really well. It's a lot smaller than I thought and seems very well made. I love the flexibility of having multiple audio output options. The optical output works seamlessly with my soundbar, and I can use the 3.5mm jack for more traditional speaker setups. I also like that it supports both digital (Dolby, DTS-HD, etc.) and analog audio, which gives me more versatility. Setup is extremely straightforward. No need for complicated drivers or software just plug it in. Considering the functionality, the price is a great value. It's not the most expensive option on the market, but it delivers the essentials with decent performance. I have other items made by the same company and never had any issues and also found there customer service A+. Highly recommend this item.

Works perfectly for true 5.1 surround sound!!
I bought this HDMI audio extractor to use with my Xbox and Fire Stick and I am impressed. At first I only got stereo but once I connected the optical Toslink output to my surround sound system and changed the audio settings on my devices to Dolby Digital it worked exactly as advertised with full 5.1 surround sound. The HDMI passthrough keeps the video sharp with 4K supported without issue and the optical audio output passes Dolby Digital and DTS properly. The red and white RCA and the 3.5mm outputs are stereo only so if you want true surround you need to use the optical output into a receiver or surround system that can decode it. For the price this little box is excellent. Easy to set up, solid build and does the job. If you want a simple way to split HDMI while still getting proper surround sound I highly recommend it.

Don't waste your money
This didn't work for me, it did extract the sound via an optical cable however the HDMI signal didn't connext, also it is in no way labelled as it is shown in the pictures, it has zero labeling on the devive which isn't a huge issue but is a pain and means even if this worked correctly I would still mark it low.

Works with SKY puck
Used with a Sky puck to extract the audio to a soundbar with the digital optical output and the HDMI to a projector. Works for my usage. Seems well made, been using for a month now and no issues so far.

Not compatible with my TV.
This HDMI Audio Extractor 4K x 2K@30Hz HDMI to Optical Audio Adapter is very good, but i have to send item back as I have some different connections on my TV so wasn't compatible with the Adapter. My fault for not checking connections properly. Prompt delivery though.

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.

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.

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.

Still have a hum in the sound. Not sure if it’s my equipment or what.
