ARC sound/volume drop out - intermittent

Recently I have noticed the volume drop on my Arc setup. It is for a few seconds only and the sound drops to barely audible (it does not cut out completely)

In the last few weeks it has become increasingly more frequent in occurence. 

It happens either when the input is just regular TV or from a HDMI input from a n AppleTV

local button control is disabled

I dumped a diagnostic event once it happened this evening : 2071955409

 

Any help would be appreciated

    Try this:

    Disconnect everything from the TV and unplug the Arc and TV from power for a couple of minutes. Plug everything back in but keep everything disconnected. Make sure CEC is enabled in the TV settings. Run TV Setup in the Sonos app and follow the app instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect the Apple TV to the TV.

      Did the solution work? I seem to have a similar situation. Recently the sound started intermittantly dropping off for about 2 seconds then comes back on. I have an Arc SL and 2 One SL speakers.

        I had this problem, I disabled sonos voice commands and no more problems since.
