About a week ago, I think with the last update when ever windows pops up a notification the Sonos Windows app stops playing and I have to go into the PC app and right click the song and select play song, simply clicking play will not work even if the queue is full.
Now I have two rooms setup one room (PC) is with a play bar, 2x sonos1, and a sub which the bar is wired to the router and is the primary output for the PC. The other room is just one play bar. If both rooms are playing at the same time “party mode” only the one set for the PC stops play.
No problems if I am streaming audio from any other source on the PC. Similar problem with my Android phone. Music stops with notifications but I don’t exactly when it happens.
