tvos17 Sound Issues

Not sure if this relates but found that the tvOS 17 update changed my audio settings within the appletv itself. If particular there is a setting to “Reduce Loud Noises” in the audio settings section that I had turned off previously but it had been re-enabled creating a terrible tinny night theater mode. Why this mode even exists is a mystery and why the update decided it needed to re-enable it is even more perplexing. Anyway I disabled the silly mode again and everything is back to normal.

I had the same problem after updating the atv! lg tv+atv 4k 3 gen+sonos arc. Resetting settings, updating, changing the resolution on atv did not help. The problem was solved simply by switching earc/arc! Moreover, switching to arc turns off atmos! turned it on again and the crackling noise disappeared, atmos returned!

I’m having similar issues on my Apple TV 4K with my LG C2 and Sonos Beam setup when change formats setting is off allowing Dolby atmos any content in 5.1 consistently cuts out every few seconds making it unwatchable but Dolby atmos is fine however when I disable Dolby atmos my 5.1 audio is completely fine and works as normal it’s only the Apple TV 4K 3rd gen that does this as every other device works perfectly in my setup :(((

Similar audio issues after upgrading to tvOS 17. LG C2 with Sonos Arc + Sonos SL surround + Sonos Sub. Everything worked very well with tvOS 16 with the audio settings set to Atmos when available. Now, with 17, the dialog channel is now sent to the surround speakers when listening to non-Atmos content. Atmos content seems ok. Turning OFF Atmos in the audio settings seems to fix the issue, but is NOT a long-term fix.

Learning my lesson on being an early OS upgrade adopter.

Anyone any further forward with this? I have the same issue with an Apple TV 4K (A2843), LG OLED and Denon AVR, I recently needed to start switching the HDMI sources via the TV rather than the AVR, and to have ATMOS sent through, enabled eARC, this then caused the crackly poor audio on everything from the ATV with a Stereo audio track. I know it is the ATV as the PS5, Cable box etc all pass through Stereo with no issues, again this seems to be related to TVOS 17 - currently running 17.4 (21L227), as it wasn't present before. It seems to be an issue with eARC in particular as connected directly the AVR there are no issues.

I have a similar issue after updating to tvOS 17.

I have an Apple TV 4K 3rd gen. Sonos Arc. LG b2 oled.

The sound on non atmos contents like 5.1 or stereo crackles and the sound is distorted. But on atmos films it’s ok.

But when I turn off eArc on the lg tv the non atmos is ok, but the atmos content only plays as 5.1.

It was ok before the update, I have also reset both the lg tv and Apple TV and no joy.

maybe a issue with the update ?

Has anyone resolved this issue? Our setup is incredibly basic: AppleTV 4K to Projector to stereo analog (projector does this conversion).

Everything was great on TVOS 16 and older, but as of the TVOS 17 update it sounds like the audio is an ultra-compressed low-bitrate MP3. It's absolutely unusable. I have completely eliminated any other item in the configuration from being the source of the issue (dropping in a Roku right where the AppleTV usually sits in the chain produces perfectly fine audio - so it is definitely the AppleTV at fault.)

Having a similar experience. LG C2, Bose 900 and AppleTV 4K 2nd Gen and since tvos 17 update having sound quality issues on Dolby Atmos settings. Most notably sports the vocals not coming through center channel it seems. Overall sound quality is disappointing. Not an issue if using source other than AppleTV.

Hey Apple, it’s getting very commonplace that you can never figure out audio on your Apple TV units. I have the same issue as everyone else since the update. Atmos works fine, anything in 5.1 goes to stereo PCM. If I just use the Apple TV app directly off my TV both Dolby 5.1 and Atmos work fine. Incompetent much?

Apple separated Atmos and Dolby digital 5.1.

I don't understand why their device cant detect automatically the content signals.

Also before this dolby digital 5.1 was detected as Multi Channel input.

The update is total mess

Similar problems here too! I can’t get 5.1 at all… plays as Stereo PCM. Worked fine before the update. I’ve also learnt through other forums that this was an issue in the betas! Now that it’s out to the public hopefully it can be fixed soon
