We have had the Sonos System for over a year now, and within the last 4 months the DVD player has begun cutting out periodically before coming back on. It only happens while playing DVDs, no other sources are affected. I have scoured the help section and tried most of the fixes I saw there, with no luck so far. It is a Sony Blueray/DVD player, playing DVDs, connected to a Beam, Sub, and 2 One Sls. The Beam and Sub are connected via Ethernet. I sent a diagnostic earlier, 178377687. It just cut out again while I was typing so I sent another as well, 1816949457.
