Diagnostic number 479729184.

Hello, for a while now my Sonos sound bar has been cutting out in the middle of songs (played from all different platforms including Sonos radio, pandora, and YouTube music). It never happens when watching TV. I thought it had to do with our internet being slow and the music buffering, but today I was listening to music through the sound bar and another speaker in a different room. The sound bar would cut out while the other room continued playing. When it cuts out, it lasts anywhere from 2 seconds to 20 seconds. Today it has been doing it worse than I’ve ever heard it. I submitted the above diagnostic while it was happening. Can anyone explain why this is happening and how to fix it? Thanks!
