Playbar crackling sound

I have a 5.1 setup (playbar, sub, 2 play:1s). Recently, the playbar has a crackling and static like sound coming out of it when I watching cable tv (cox). I have an optical cable running from the playbar directly to the TV. Please help.

The only other source I have hooked up is Apple TV and that works great with no audio issues.

Should have said, mine is an LG TV source.

Hello there, nholder79. Thanks for posting and welcome to the Community. Can you tell us the make and model of the TV you have directly connected to the PLAYBAR? Does the optical cable go directly between the PLAYBAR and TV or does it go to another device? The more information we have the better we can assist. Thanks!

nholder79: Thanks for the details. Are you experiencing dropouts or delays? Would you mind submitting a fresh diagnostic report? Does this happen regardless of the audio output (PCM or Dolby Digital)?

Alternatively, if you have a moment, you can give our support technicians a call and they will be able to take a closer look in real time with you.

Having the exact same issue with an LG OLED E7P TV. Everything was working just fine and suddenly we get a "pulsing" static only signal from the TV source. Apple TV and Bluray work fine. I'd love to work with support but apparently it's considered appropriate at Sonos to completely shut down support for an entire day!

    I had the same issue with playbar/sub/surround setup and finally fixed it after 6 months.

    Sound was flawless for a few years and then about 6 months ago i started getting static from TV source only, and oddly only on certain channels. I went back and forth with tech support, running diagnostics, swapping out optical cable, connecting to cable box rather than tv, adjusting every audio setting on TV and cable box, and nothing really worked. I was about to give up and a tech suggested doing a factory reset of the playbar (instructions are on this site somewhere). It solved the problem instantly and the sound is back to being perfectly clear.

    Tech support was very responsive and helpful, i just with they'd suggested this first - it seems to be a not uncommon issue. Give it a try!

    Same for me! Could be the Cable Box (Contour COX)? Or HDMI cable from Cable Box to TV? The crackling sound never occurs on Sonos music or Apple TV / Blueray but just on TV!

    I'm also experiencing this problem. My LG B7 TV with a Comcast box connected via HDMI has the SONOS Playbar connected directly via optical. The crackling comes and goes, but only seems to happen on the Comcast input. The AppleTV and BD player both seem fine.

    I submitted a diagnostic report within 5 minutes of it happening. Diagnostic #1313994970.
