I have been a Sonos owner for about 6 months and while I love the system overall, it's extremely frustrating that my Playbar experiences audio dropouts consistently. The dropouts are never more than a second or so, but this should not be occurring with a $2000 sound system. My system setup is a Samsung KS8000 feeding audio through the OneConnect optical port directly into my Sonos Playbar. The dropouts occur when using the Samsung native apps (Netflix, Plex, Hulu) or when using a third-party set top box like Fire TV. I do not have cable TV so I can't say for certain whether the dropouts are occurring with cable.
I just had the dropout occur this morning, and I submitted a diagnostic immediately after, confirmation number 7803047. I would like somebody from Sonos to get in touch with me as I would like to resolve this issue as soon as possible.
