Just installed Samsung 4K TV, Bose Soundbar (optical) and Apple TV 4K (using 4K HDMI) in new home. While watching streaming apps on ATV4K the sound cuts out for 3-4 minutes and then comes back. It's more prevalent on Peacock app, but happens with all of them. This is happening on another system (exact same set up) on the patio as well. Any thoughts on how to fix this?
I am experiencing the same issue which everyone else has described. AppleTV 4K attached to 2021 Samsung Q80 with Samsung Sound Bar and sound drops out when viewing.
I contacted Apple Support today and they informed me that this is a known issue and Apple Engineers are working on the problem and it will be rectified in a future software update.
The temporary workaround (as has been suggested earlier) is to Change Audio Format to Digital 5.1 on the AppleTV 4K.
I tried this solution, and my sound drop out issues have been resolved. I guess it is just a matter of waiting for the fix to be implemented.
I’m not sure about others, but the issues with my set up are confined to programming in Dolby Atmos. Also, thanks for all of the workarounds but downgrading to 5.1 or stereo is not a solution and defeats the purpose of having Atmos-capable equipment and fully enjoying enjoying Atmos content. I’m beginning to believe that the lack of a solution is an extension of the animosity between Apple and Samsung who have been fighting for years (and $billions) over certain intellectual property rights. Apple, please be the adult in the room and fix the problem!
I too have this problem. Brand new QN85 TV and a Vizio sound bar. I mess around with closing the app, changing audio tracks. I got SO fed up today because I couldn't get it to work no matter what I did. I was replacing my Roku which had bad networking with the Apple Tv - which has major sound problems. I guess FireTV is the way to go if I am going to use Youtube TV....
Mea culpa. Maybe. I e upgraded to TV OS 15.2, AND replaced the cable from the Apple TV to the Samsung TV. No more sound drops! I’m betting it was the cable. Although I used an HDMI 2.1 cable from the HDMI eARC out on the TV to the Sonos Arc soundbar, I was using the HDMI cable supplied from Sonos (packaged with the Arc) from the Apple TV to the Samaung. I guess I (foolishly) thought that the cable with the Arc was 2.1 - apparently NOT! Now using two known HDMI 2.1 cables, and no no more sound drops. Maybe it was the OS upgrade, maybe the cable. Doesn’t matter. Seems good now.
I didn’t want to go to stereo or change bit rate and lose quality, but discovered the option to turn off the ‘Change format’, so it sends uncompressed. For me it was defaulted to Dolby 5.1 but now with the option off, sound is steady.
I'm interested to know if it work.
I can confirm updating to 15.2 fixed this issue for me and now I’m back to atmos with no dropouts.
Harvey….Do you have regular HDMI cables or running all HDMI 2.1 cables?
