OREI 4K 60Hz 18G HDMI 2.0 Audio Converter Extractor - SPDIF + 3.5mm Output - HDCP 2.2 - Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision, HDR10 Support (HDA-912)

Great little product. I was confused by the hook ups, as I was thinking I could bypass ARC from my soundbar to my projector (the projector is non-ARC) and using the volume control on the soundbar causes the projector to go to its menu and it's hard to switch back the HDMI input after it does this; took about 3 attempts and was a pain. So what I had to eventually do is hook up the soundbar via it's optical out to the extractor's optical output and plug the projector into the HDMI output of the extractor. No Atmos over optical but I never really used that, but the 5.1 sound and picture quality are excellent and no more issues with the ARC or CEC function from the soundbar as there was no way to turn it off. Very happy with it and solidly built.

works great! didn't have to replace my old receiver. I can now use my Xbox X to watch Ultra HD discs using optical sound with no audio lag because the sound doesn't go through the TV first

I'm only using this for HD video, nothing 4K in my system, but it works flawlessly.It's odd that they included a wall wart power supply, when a standard USB power cable (USB 2.0 Type A Male to DC 5.5 x 2.1mm DC 5V Power Barrel Plug Connector) works just fine, and frees up an electrical outlet. I already have a multi-outlet USB charger plugged in, ready to go.

Purchased with the intent of pairing a Streaming Stick+ from Roku with an older TV which somehow doesn't feature ANY audio output/pass-throughs. Taking the HDMI signal spit out by the Roku and injecting it into the HDA-912 results in a picture being sent on through to the display as well as a usable audio output to which my stereo is happily connected via analog.Note: if provided by the source, audio IS still sent through the HDMI output of the HDA-912 - think of the device as a means of adding connectivity rather than *splitting* the audio and video signalsPros:>Sturdy metal enclosure>Provides audio connectivity otherwise not available for displays lacking audio outputsCons:>Audio is "extracted" from the input HDMI signal yet remains present in the output HDMI signal with no apparent way to disable>Included SMPS adapter goes straight from mains to barrel jack - since it's only 5V @ 1A, a USB Type-B power input (+ Type-A to Type-B cable and associated brick) would be prove far more versatile

I purchased this so that I could extract 2.0 (stereo) PCM audio from the toslink connection to a wireless headphone transmitter. (The transmitter accepts ONLY 2.0/PCM input.The expectation:That I could insert this device between the output of a streaming box, which can output surround audio, and the receiver - and the 'untouched' surround audio portion on the HDMI input would continue through to the HDMI output connection - and the the device would 'convert' the surround audio signal to 2.0/PCM and send it out the toslink output to go to the headphone transmitter.What actually happens:If I select the 2.0 switch option on the device, I DO get a down-converted 2.0/PCM signal from the toslink output as needed. But here's where the problem is: In choosing that 2.0/PCM switch option, it ALSO then output ONLY 2.0/PCM audio on the HDMI output connection going to the receiver. So I then lose my surround audio going to the speakers. If I choose the surround switch option on the device, surround audio signal is restored onto the HDMI output...but then I have no 2.0/PCM signal on the toslink output again, so then the headphones don't work.Instead of labeling this as an "Audio Extractor", it should be labeled as an "Audio Converter" since the switch setting seems to convert in the incoming audio signal to the switch setting and then sends that converted signal to to the HDMI-out and the Toslink-output.

Does a great job with the AV signals. Well priced and compact. Extracts HDMI audio to multi-channel optical or L/R analog audio. Pass through optical up to 4K.

I have had issues trying to get my firestick 4k to work with my projector and sound system. This converter extractor worked from the time I plugged everything in!!!! Only issue was that the power supply didn't have the "plug" so I could plug it into an outlet. I borrowed one from one of my other phone cords.

Just outside the warranty period and this unit is no longer working. I have other OREI products, and they work well for what I need. However, this one doesn’t seem to hold up as well as the others. It started with my TV no longer getting a signal, then it would come back intermittently, which is absolutely unusable. At first, I thought it was the cables, but after pulling this out of the lineup, everything worked again (well, except the audio, of course). Sadly, it works well but it doesn’t seem to last, as seen in other reviews. I hold out zero hope since it failed so close to the warranty period. Your mileage may vary, but expect about a year, if not less.
