OREIeARC 4K 60Hz Audio Extractor Converter 18G HDMI 2.0 ARC Support - HDCP 2.2 - Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision Supported (HDA-927)

I purchased a new 4K TV (98” TCL) but I am still pairing it a non-4K non-eARC receiver (Denon AVR-5308ci), so I needed an eARC extractor to get the audio from the TV to the receiver. After researching various recommendations on the AVS Forum, it sounded like the recommended devices were the devices made by ThenAudio and HD Fury, which run the int $250-$400 range.I purchased the ThenAudio Zone2Pro from their website, but it performed poorly. Half the time, I would get no signal, or the signal was unstable and would exhibit drop-outs if it was anything other than 2 channel stereo. The problems were worse with Apple TV, but also my Sony 4K Ultra HD player. Worst of all, sometimes when the sound was not properly outputting, I would suddenly output very loud tweeter-blow-out white noise that would generate complaints from everyone in the house.I didn’t know if the problem was with the ThenAudio eARC extractor, the TV’s eARC implementation, or if eARC itself is just an unreliable inconsistent technology. The only way to tell was to get another eARC extractor. I didn’t want to buy the HD Fury, so I decided to buy the best reviewed eARC extractor on Amazon, which was this OREI, at less than 1/5 the price of the audiophile Zone2Pro.I didn’t have high hopes for it, but I’m glad I bought it. It worked exactly the way it was supposed to, in a very consistent manner, without any of the problems that I had with the Zone2Pro. Rock solid reliable eARC extraction, without any of the speaker-damaging white noise or extraction failure, and at 1/5 the price. This may not work as well for others, but for,my combination of equipment, it worked perfectly, and way better than the ThenAudio Zone2Pro. I don’t know how well the HD Fury product works, but given the much lower cost of this OREI product, I would certainly start here with the OREI.Edit: I reached out to ThenAudio to see if there was an issue with the Zone2Pro. I did flip a DIP switch on it to turn off Dolby MAT. I let you know if that helps with the white noise surges and drop-out. Still, the OREI is way cheaper and achieves the desired result.

I couldn't find a clear cut answer so hopefully this will help. If you are looking for a audio extractor that will help with the DTS issues of a LG OLED and SONOS arc combo, this product will not work. Unfortunately your only option is the HD Fury.I'm sure this product works fine for older tv's and audio receivers so don't take offense to my review with that. Just trying to help people with the same issue I have.

I got this to eARC enable my Marantz SR7010 AVR which has working ARC support - to my new Hisense U7K w/ eARC HDMI 2.1 support. With ARC you only get up to 1.5Gbps audio; ATMOS 5.1 core, DD, DTS, and a lesser quality version of ATMOS. Modern BD and UHD based movies primarily use DTS-MA, TrueHD ATMOS which are only available on eARC equipped systems (18-48Gbps bandwidth)I left both dip switches "On" for eARC and EDID (since my AVR supports all current audio formats) and after testing various "ultra hdmi" or "hdmi with ethernet" cables I was able to get up to DTS-MA 7.1 on my AVR - but TrueHD 7.1 would not work.Just to make sure I ordered new HDMI 8K ethernet 2.1 cables and that not impact the result. I used the eARC/ARC port on the TV to the adapter OUT 1 port; AVR non ARC port (HDMI 1) to adapter OUT 2 port.When testing I found I had to completely turn off and unplug the TV, AVR, and this adapter to ensure any change to the setup would be picked up. Once I figured this out I went through a methodical process testing various combinations of adapter and AVR/TV HDMI settings.The TV says it's outputting "MAT" which is TrueHD/ATMOS but all I get is silence via Plex app on TV. I had to switch to the embedded 5.1 audio track to get any sound.Beyond the audio; CEC mostly worked. Turning off/on of the AVR does not always work. Turning off the AVR after initially using it and turning it back on usually resulted in no audio which as only correctable by restarting everything (but not restarting the adapter).HDMI compatibility can be hit and miss and this is mostly due to the optional nature of the standard - format-wise; vendors can pick and choose what and how they want support various capabilities and that can cause issues. The older the HW the more likely issues can arise - it's just the nature of technology.To be sure I bet this can work just fine for folks who use sound bars or other non true home theater 7.1 (and/or Atmos) setups as the most they need is a low bit rate 5.1 audio track - but for those that can take advantage of all a 7.1/ DTS-MA HD/Atmos, etc. formats has to offer it may fall short for you depending upon your equipment.In reality for the price, ease-of-use, and size it's probably worth a try; it's just going to be YMMV

This fits a specific need but requires a bit of tweaking to work properly. I'm writing this review so that maybe somebody can use it to find the right combination of settings to get it to work for them (a few of the settings seem backwards)I have an hdmi running from my playstation 5 to my tv (LG C9) to get the best picture possible and an hdmi from the to my old receiver (Harman-Kardon 1565). As I understand it, the problem was that the receiver doesn't support (e)arc, so the audio got downgraded. This guy plugs in between the TV and receiver to allow the receiver to output uncompressed audio.To get it to work:flip the dials to "Out 2" and "earc on"HDMI cable from HDMI IN 2 (ARC) on the TV into "out 1" on this device. Yes, the labeling on these seems backwards.HDMI cable from "out 2" on this to a non-arc input on the receiver.I set the audio out in the TV audio settings to HDMI ARC and Pass Through.At this point the disney+ app on the TV immediately started showing up as dolby digital +.However, the playstation was still only outputting in stereo. I had to set the sound in on HDMI 1 (where my playstation was plugged in) to bitstream to get my receiver to spit out Linear PCM signal. So Playstation output priority is PCM>HDMI input set to bitstream>HDMI output set to pcm.
