Apple tvOS 17 No Sound

So I have a similar issue. Sony TV, Sonos Soundbar and Apple TV 4K using eARC. No audio issue until upgrading to 17.0 then I lose the ability to change volume with the Apple Remote. It looks like it is changing on the screen but it will not change the actual volume. For me in settings > remote it defaults to Auto. I found that if I manually change to TV via IR it resolves the issue for a few hours or until I change multiple apps. I have seen some strange behavior where the selection will go back and forth between auto and TV via IR very quickly like in a feedback loop, but I can usually get it back to TV via IR and get it working again. I genuinely hope it is an OS problem and is addressed in an update. It’s pretty annoying.

I spoke too soon. There have been a couple times since I thought I fixed this where my sound once again stopped working. And so far the only way to fix it is to power cycle the TV. It's hard to say what caused the sound to go out again. I was cleaning and unplugging cables, that's about it. Right now it's working again. My TV is an old LG, like 12 years old. But I bought a new Apple TV 4K in 2020, hooked it up to this LG, never had any issue. That lasted a few years until I moved and switch things around. This past week, I once again hooked up the same Apple TV to this old LG, and noticed the sound issues. Luckily Apple TV can connect to soundbar over bluetooth as a backup.

For me it’s more random. If I watch a trailer on Hulu, no sound. If I watch something on Disney+ but just press the home button and leave it in the background; then switch to Youtube TV; no audio until I close both apps. It’s definitely odd behavior

I would say this is not contained to just Samsung tv’s. Definitely an is with tvos17 though. I was trying to watch a purchased movie from the Apple TV store and no audio. Turned on my PlayStation 5 and booted up the Apple app and the same movie played back just fine.

I’ve been experiencing this too.

I’ve been a long time apple TV box user…. From first gen to current gen (whatever it is right now). I even got this new gen cause I thought the last gen was the problem with regards to audio. But even with the latest apple tv box we experiencing this audio problem. Its not the hdmi cable and its not the receiver. You know how I know??? Cause you can hear the little blips when scrolling through the main menu and the settings… the only thing we can’t hear is the audio from the series or movies.

I also have this issue reset and restarted Apple 4k both Ethernet and WiFi unit

spoke to Apple care who said they have heard of this issue but no solution

in fact I exchanged my Apple 128 4k Ethernet and happened with the new unit also

Just bought a new AppleTV last week. It worked just fine then update to 17.4 a couple days ago. Now low intermittent sound. Old one that I moved to the other room works great. Won’t update that one now.

Switched to the Apple app installed on the Samsung tv and no issues but without the great 4k. Definitely an AppleTV issue. Possibly a return?!?

Half of my Apps do not have audio. I’ve tried everything including resetting Apple TV, SONOS, and TV.

Are you using Airplay? If so, this might fix the issue.

Same here. Please fix Apple

Same. After the update to tvOS 17 so far it's the youtube app that loses audio.

same issue here with tvos 17 - rebooting samsung tv and apple tv seems to work sometimes. Apple should fix this asap.

Also having this problem with the Samsung/Sonos combination. Very odd and unpredictable and it doesn’t seem ti be consistent as to which apps will or won’t have sound. Definitely only became an issue with the latest software update though
