    Hi there, pgiliber. Thanks for the details and information. I believe the issue affecting your system is one that we've been talking about in the Community. Our team have been collecting information and are currently waiting on a firmware update from LG and Sony to address the problem. While it is limited to LG OLED and Sony XBR TV's it is certainly something the team is aware of and actively tracking.

    Thank you for your patience so far.

    I need help with my sound bar.  The static just started after owning the system trouble free for years. I did a diagnostic.  The number is 2132564178.  I have a Sony television.

    I looked over your diagnostic and I’m not seeing anything that stands out at a big issue. The Playbar was just rebooted 20 minutes prior to the diagnostic, so it doesn’t have a lot of information in there however. I’d suggest that you give our support team a call to troubleshoot live. They’ll take a look and see if you’re experiencing something related to what was mentioned earlier in the thread, or if it’s something else.

    Hello @Jmack3g, Welcome to the Sonos Community and thank you for reaching out with your issue. 

    Can you tell us if this only happens while you are using your Apple TV as a video source? 

    Are both your TV and Apple TV set to output Dolby Digital 5.1 as an audio format to your Sonos Playbar?

    Hello @Jmack3g,

    In the last diagnostic that you submitted to us, your Playbar is still receiving a stereo or PCM signal from your TV. 

    You may want to double-check the output settings just to be sure. 

    Does the crackling happen when you use a music source like Pandora or your Music Library?

    I had this issue and submitted a diagnostic about 2 months ago. The issue stopped but started again in the last few days. My Tv is a Sony XBR 950. I’m using an Apple TV 4K and a Sonos Beam. 
     

    My diagnostic number, which I just submitted, is 766479866. The issue does not happen with YouTube TV and it does not happen with streaming music from any music source. It happens on occasion when I’m playing something from Apple like an iTunes Movie or something from Apple TV+. I believe it happens with Netflix as well as Amazon Prime. I don’t recall it happening when streaming a TV show from Fox Now or any other TV channel app.

      Hello @Keydet71, 

      Thank you for reaching out to the Sonos Community with your diagnostic report. 

      Does this only happen when you are streaming video content via the Apple TV? 

      Do you also have smart  TV apps, a DVD player or broadcast television that you can test the audio on?

      Is there any chance that the Apple TV is broadcasting straight to the Sonos Beam via Airplay rather than through a wired connection to the TV?

      I am also having this issue, with this exact setup (possibly a different XBR TV), since the most recent Sonos update. It does not occur on youtube, and it consistently occurs for me on Netflix. Forcing the Sonos to reboot seems to resolve the issue temporarily - but I’m not entirely sure.

      I am definitely not broadcasting over Airplay. This issue is miserable, and it makes Netflix unwatchable with the Beam.

      Hello @taronish,

      Are you able to verify that both the Netflix app and the Apple TV are outputting audio in a supported format for Sonos?

      Either Dolby Digital or PCM/Stereo?
