Sonos Arc Ultra Crackling sound

Just wanted to add to this issue, as I am also experiencing it and it is very annoying. 

You constantly feel on the edge of: “When is it going to happen next?”
I don’t know, but my 1000 EUR Soundbar should not do this - it’s like a static / crackle / or high pitch pop at random times.

Definitely noticed it during a silent movie like A Quiet Place ( any iteration ).

Do we have any update from Sonos so far? 

I haven’t gotten any updates. I have noticed that it doesn’t seem to happen when I am streaming Netflix, prime or Paramount+, so I’m beginning to wonder if it’s my DIRECTV receiver (since I have gone through three arc ultrasound bars and a new TV and it is still occurring). I just ordered a new receiver today and it should be here in about five days. I will update this post with The results once I get it.

​@Steven S. and ​@MC74 no solution provided yet. I received an email on 12/20 stating my initial case number was forwarded to a level 2 support team and engineering is currently troubleshooting the issue. As far as streaming services, I’ve heard the pop sporadically on Netflix, Paramount+, Peacock, Disney+, and Apple TV. Keep in mind I use an Apple TV to stream, no cable box and it’s connected to a LG C3. I don’t have this issue with the Arc connected to my system. 

​@FCP and ​@Steven S. I’m have just noticed some popping while streaming. It’s not nearly as bad as when I am watching Directv, but it is clearly not isolated to cable. I was also told that my case had been elevated to level two support as well. I was told I would be receiving an email from them. That was weeks ago and I have heard nothing. 

Contact them again with your case number (don’t post it here) and ask for a status update.

Just wanted to add that it seems the popping / crackling also happens when listening to music over WiFi it seems like.

How does one "Captures a diagnostic?"

From the Sonos Support site:

The small pop / static also happens when on the Home screen with Apple TV and no sound is playing.

It’s a split second, but it’s annoying enough to keep you on the edge and think: when is it going to happen next.

Weird…

I have a Chromecast, LG TV and the Arc Ultra

I was on Netflix watching Mission Impossible last night, the first one. It started crakling so bad, I changed the audio output on the Chromecast to use stereo so I could finish the movie.

Changed the setting back to the way they were.

Mission Impossible 2 ? Not a problem.

I’ve had the Arc Ultra for a little mote then a week now, watched lots of movies, played on the Xbox, listened to music almost 24/7 on it, only Mission Impossible made crakling sounds… so far.

Both of them are Dolby Digital Plus 5.1 movies (according to the Arc Ultra).

Nothing changed in between the viewing sessions, I watched the first one and the second one right after.
