    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.

    Where it doesn't happen when PCM is set on TV it has to be something with a 5.1 compatibility. That's what I have found from my troubleshooting. I still leave it on 5.1 because is sounds way better minus the intermittent crackling.

    I also see no sign of cracking on PCM, its definitely a 5.1 issue, I received an update last night to 8.5 build. I would assume this release has no fix Sonos folks?

    Would Sonos have any update on this incompatibility of the between the Playbar and 65" OLED65C7P?

    I am having the same issue on my new vizio tv. Comcast X1 box with HDMI connected to tv. Tv connected to play bar through optical. Output on box set to 5.1. Input and output on TV set to 5.1. Will submit a diagnostic report as advised.

    After submitting the diagnostic, you should either post the number here, or call in to Sonos and give them the number....

      Hi,

      I have also been having this issue for the last year or so (since purchase of the Playbar). The audio is fine when playing music, but while attached to our 2016 Vizio P65-C1 65". I purchased a new optical cables and tried cleaning them, but that didn't fix things. The Playbar is hooked up via Ethernet.

      The crackling sessions happen about once every few days. When a crackling session starts, pausing the DVR, then playing will fix the issue temporarily. It will then happen a few minutes later, repeatedly. It is very obnoxious and disappointing.

      Digital out was on the TV was set to "Auto", but based on other's comments above I just set the audio out to PCM.

      Please let me know if there is a fix. I'd like to buy 2 Sonos One's for surround sound, but I'm reluctant if this keeps up.

      Thanks in advance.

      May I recommend that you submit a system diagnostic within 10 minutes of replicating this issue, and contact Sonos to discuss it. There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
