OREI eARC 4K 60Hz Audio Extractor, Extract Dolby Atmos Convert Sound bar 18G HDMI 2.0 ARC Support HDCP 2.2 Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision, HDR10 Support for Sonos Bose (HDA-929)

​"Si vous avez un excellent récepteur audio (comme un Harman Kardon ou Yamaha) qui ne supporte pas la 4K, mais que vous ne voulez pas le changer, cet extracteur est la pièce manquante.​J'ai 40 ans d'expérience en électronique et j'ai tout essayé : c'est le seul boîtier qui me permet de garder mon image 4K HDR tout en envoyant un son 5.1 parfait à mon ancien ampli via le port HDMI 'Audio Out'. L'image est fluide, le son est riche et sans aucun délai (lag).​L'installation est simple, robuste et le résultat vaut largement l'investissement. J'ai maintenant l'impression d'avoir un système à 10 000 $ pour une fraction du prix. Très satisfait !"

1. Been struggling for so long to get the setup working but this product resolved my issue.2. Although its been just half an hour i have set this up but it works already and flawlessly.3. I'll talk about my issue and how this resolved it:3.1 I’m contacting my cpu to my 65’ sony tv, which is connected to my bose 900 dolby atmos setup, but i was only getting stereo output.3.2 Have trued dolby access too but it gave me choppy audio output, which keeps disconnecting in between3.3 My ps5 gives me flawless atmos setup with the tv but pc was always an issue3.4 I connected hdmi 2.1 from my graphics card to source in the product, then bose hdmi to earc/arc on the product, then third cable to hdmi 1(can be any hdmi port) on tv3.5 opened the dolby access app and selected home theatre, it showed ready!3.5 keep the access app open (minimise it) and it just worked4. product pricing is definitely overpriced but nothing to complain on functionality front5. Couldn’t be any more happy with it6. Definitely recommend to anyone having this issueUpdate after 2 months usage1. You have to unplug your tv first, yes unplug even the wall socket, let the hdmi get reset in 2-3mins2. Plug in all the cables, switch on tv first, than the pc3. Open dolby access app, minimise after setting up your home theatre and it just works4. Only issue i faced is if i leave the computer idle fir a while it automatically stops working and then i have to repeat the whole process again of setting up, it maybe specific to my setup i dont know5. Strongly recommend for anyone looking for taking highest quality audio from their pc

They sent me the BK-929u instead of what I ordered. I decided to pug it in and see if it would correct my Apple TV-Bose soundbar-sound bar issues. I have messed with this set up for at least 20 hours over the years. Sound dropping, no sound, un pluging, rebooting, no volume control. I was just about to just buy a new TV. This thing fixed everything! I now have Atmos sound option on Apple TV, my sound bar works when I turn on the tv as well. So far so good. Worth every penny.

Ideal se teu TV não suporta ou não deixa passar algum tipo de formato de audio para o equipamento de som.

Does work but comes with American plug adaptor, not much use in uk, had to buy another uk adaptor
