OREI eARC 4K 60Hz Audio Extractor, Converter Sound bar 18G HDMI 2.0 ARC Support - HDCP 2.2 - Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision, Dolby Atmos HDR10 Support (HDA-931)

It worked once over eARC, sounded great. Then, after unplugging and plugging it back in, it no longer worked over eARC.

If you're setting up a real home theater, with a projector, not a TV, you need a way to send the streaming or Blu-ray video signal to the projector and the audio signal to the home theater audio system. Sounds simple, right? Wrong. TVs have audio out HDMI for this purpose. Blu-ray players do not. So your choices are to buy an expensive receiver or to buy an eARC extractor. If you search "eARC extractor" in Amazon, a ton of choices come up, but don't be fooled. Most of them don't actually separate video from eARC audio. I was about to buy an HDFury Arcana for $300 when I found this OREI option for about $100 and decided to take a chance. Glad I did - it works perfectly.

It help for a few months then it stopped working not sure it’s worth the money

I recently purchased this product mainly to get Dolby Atmos. I have Nakamichi Dolby Atmos Bar and Roku 4K Ultra device which I had connected to my projector but the projector does not support Dolby audio. I was looking for alternatives and came across HD Fury 4K Arcana but is currently 300 bucks. This extractor is very less.The setup was easy. Once connected I just have to change few options on the Roku Audio. After the set up I closed the Netflix app and opened again as mentioned in youtube video and I could see Dolby Atmos now where as earlier it was showing 5.1Example movies : Extraction, 6 underground.Very satisfied with the product.

I had very high hopes for this little box, as it seemed poised to solve multiple problems in my AV setup. Sadly, the HDA-931 is only half-baked and incapable of crucial parts of its claimed functionality. Specifically, advanced HDMI audio formats (e.g., uncompressed 7.1) do not pass through the device correctly. Simpler formats work (e.g., AC3 and DD+Atmos), but that’s the same level of functionality as regular ARC.I tried this device both as an input-side HDMI-to-HDMI audio extractor, and as an output-side eARC-to-HDMI translator, with equally disappointing results. In either scenario, the HDA-931 presented only 2.0 sound at its HDMI Audio output, despite the game console sending uncompressed 7.1. Surround sound works if I switch to Dolby AC3, but that introduces a significant encoding delay, and again, is no improvement over basic ARC.The one setup that I haven’t tried (as it’s irrelevant to my equipment) is using the HDA-931 as an input-side HDMI-to-eARC Soundbar extractor. The optimist in me says maybe that’s the one configuration that actually does work with advanced audio formats, and that’s largely the reason I’m allowing this device a two-star rating instead of one.A side note on usability: The HDA-931’s single-button interface is far too simplistic for everything the device attempts to do. The "eARC auto detection" does not work reliably, and I’d prefer just having a switch to set the unit’s operating mode. Trying to re-task the HDA-931 from eARC translation to audio extraction is a pain, because there’s no reset-to-defaults button.Overall, my gut feeling is that the HDA-931 might be just a few firmware fixes away from working properly in all its modes, but the device lacks any field-update capability, so there isn’t much hope beyond waiting for a replacement model to come out. As such, I cannot recommend this device.

I use eARC/ARC pattern generator and Sony soundbar to test the box functionality. In ARC mode, it can display audio correctly and up to DD+ atoms. And the eARC light also be turn on. But it will be failed and no audio output in eARC mode. I have no idea why eARC can’t be detected….. Does anyone have any suggestions?

It worked sometimes and didn't most of the times. Has to return

I ignored most of the reviews here and tried one because I was desperate to get eARC audio out of NVIDIA Shield TV. The other option is HDFury Arcana which will cost more than double.Anyway I could never see eARC light lit up. With HDMI 2.0 cable I see 7.1 led is on. But at the audio end software say 2.0 (Stereo). Same with Optical out (5.1). Getting only Stereo. Good concept. But untested product it looks like
