Intermittent, very brief cut out of sound from Samsung TV through Playbar. Happens on all TV sources - cable box, android box, streaming services. Optical cable connection. Does not occur while playing music. 

Sounds like your TV may be sending the wrong signal to the Sonos via the optical connection, at times. I’d be double checking to ensure that the TV is locked down to Dolby Digital only on the output, and also the settings on all the devices feeding the TV as well, since across optical, there is no ability for the Sonos to ‘tell’ the TV which formats it is capable of processing. 


Hi @schaser 

Welcome to the Sonos Community!

It may also help to unplug your TV from power for at least a minute.

I hope this helps.
