Sonos Arc Ultra Crackling sound

If you rewind do you get the same noise at the same place?

Capture a diagnostic as soon as possible after the noise and contact Sonos support (not here) to have it looked at.

Unfortunately I don’t get the same noise when rewind. I called them after the 4th time hearing it, ran a diagnostic and couldn’t find any issues. 

I just had it happen to me as soon as I turned my tv on! No audio even playing thru the Arc Ultra. I turned everything off because it sounded like it was going to damage something. Same thing, I upgraded from arc. Connected to 2 subs. I thought I’d be happy, but it’s been one shortcoming after another with this setup. I’m getting really bad audio lag across multiple different streaming services and streaming “cable” too. And yes I tried lip sync and audio delay settings on my tv. Never had any issues with the arc. 

What did Sonos Support say, when you called them about these issues? 

​@Airgetlam they couldn’t find anything wrong with the system. Since I couldn’t duplicate the issue, they told me to keep monitoring and run diagnostics if I hear it again. Since that phone call, I’ve heard it three times. I ran two diagnostics yesterday and saved the codes, I’ll try to call them again later today. 

​@Sringer7 did you call Sonos?

Try changing your audio to automatic from compressed. I had the cracking noise when fast forwarding and playback mode on my Sony 77”. No problem since I made the change. 👍🏻

I have this same issue with my Arc Ultra. It happens very, very frequently. It’s like the sound hits some kind of technological wall and clips itself off. It’s terribly annoying. I will contact Sonos shortly.

​@Cnote I will give it a try

​@CovingtonMusic I’m hoping its software not hardware
