I was listening to music at about 10% of full volume when all of the sudden the music paused mid-song and then a few seconds later out of nowhere came this horrible screechy/scratch noise. The noise was at full volume even though I was listening just moments before and a low volume.  It sounded like a demon had possessed my system.  I have a a paired set of first gen sonos ones, a single sonos five, and a sonos arc.  This happened while listening on the paired ones and sonos five grouped.
