How to stop crackle/ static on sound bar

By default, the Apple TV will send uncompressed multichannel LPCM, and this has been working fine for me since December - until the recent Sonos update. I’ve just attempted to force the Apple TV to reencode this as Dolby Digital (which sadly will reduce audio quality), and I will post an update if this either seems to actually resolve the problem or if it doesn’t - sometimes the issue will not immediately occur, so it is difficult to troubleshoot.

Since Netflix is an app on a closed platform, I’m not sure how you suggest that we can verify anything in particular about audio encodings or formats of the application - I didn’t even try, but if you know of some way, let me know, and I will do my best to give you that information.

It seems very likely that is a bug introduced - or reintroduced, since the other reporting user said he previously had the same issue - by the Sonos update, or perhaps some interaction between the Sonos, the Apple TV, and the Sony television, which is now surfacing due to the update.

I forced Stereo from the Apple TV and the problem seemed to go away for me. If I switch it back, I get the static again almost immediately.

I’m having the same issue with my sound bar and two 1s connected to Apple TV-diagnostic 591972843. I called tech support yesterday and they told me to restart my router, which worked for 15 minutes then the static came back again. He also told me to buy the Boost, which I did, but now I’m realizing this is probably due to a bug, so I’ll be returning.

Considering the price tag on these speakers, this is really unacceptable and a big push to move to Bose. Please address this ASAP.

But Stereo doesn’t produce surround sound right? This is insane 

I don’t have this issue from my Apple TV. But I don’t have a Sony TV, either. 

So I am overdue to post an update on my situation - for me the problem hasn’t come back, as long as I have the Apple TV reencode the audio as dolby digital. I think this still means it is fundamentally a bug either on the Sonos side or with the interaction of the Sonos, the AppleTV, and the Sony TV set. This works for now and I can watch Netflix again.

Before this workaround, it was super irritating, because my Sony TV won’t let me use internal speakers when the Sonos is connected - even when I set it to “TV Speakers”, it immediately goes to “audio system active”, which means that to watch Netflix before, I had to unplug the BEAM.

I have my Apple TV audio set to Dolby Digital but still hear the fuzz. It goes away when I change the output to Stereo, but that disables surround sound, which was the whole point of getting Sonos.

Hello, could use some help here as well. This only started happening after upgrading to the new Sonos S2 app which triggered a firmware update to my system. Since then my audio has been cracking on my playbase via an optical audio connection to my Sony X950G. Diagnostics report: 83800953

Using an Apple TV 4K with Dolby Digital set on the TV and Auto on the Apple TV for everything else. 

The answer and what WORKED for me. Step 1 - update your firmware. Your oled has an internal

speaker so go to to settings and go to sound an ensure under audio outputs it doesn’t say tv sound but audio speakers and that solved the issue. What’s weird is all up until today I had no issues but when I changed to audio output then my tv did work. Try it. I have a Sony a9g oled 

I’m afraid the firmware across my TV and Sonos are up to date. Also the TV’s settings are correct, if they were set to the internal speakers I wouldn’t have run into this problem in the first place :)

Are there any Sonos admins who can help?
