What Sonos devices do you have in your system? Does the music cut out only when streaming from your music library or does it also happen when streaming from music streaming apps? What types of audio files do you have in your music library?

Thanks for taking notice of my post. I’m streaming from a local cloud drive to my stereo through a Sonos Port. My files are a even mix of WAV and MP3 files. I don’t typically stream from a service so I don’t know if this would happen when doing so. This just started since the recent upgrade. It also doesn’t happen if I go back and play the song as a single and not through the playlist. 

Have you noticed if the problem happens more when playing the WAV files? Have you tried unplugging the Port from power and rebooting your router?

 Have you looked at the Now Playing screen on the app when this happens to see if there is any error message?  I used to get an Encoding error at times when playing Atmos.  Don’t remember the exact wording of the error message.  Soon after that Encoding error message the next track would start.  Repeating the same track usually did not generate the error again.  The difference from what you describe is the timing of the error; It was not at a repeatable location in the track so no 20 seconds before the end of the track.

I don’t see an error message in the app on my phone when this happens. I’m not running the interface from my PC. I did try to replay the song from the playlist when it first happened by going back once the next song started. The second pass also terminated early. That’s when I went to my music library and played it as a single from there. It played from the library correctly. This may tie in with the loss of a directory in the library but I can’t tell when that disappeared. I haven’t reset the unit because it’ so intermittent that I only notice the fault on songs that I’m paying attention to while doing other things around the house. I don’t suspect the router because I’m not seeing anything strange with my apps while I’m working on the network at the same time. 

The problem only pops up intermittently, once every 20 songs or so. I haven’t tracked it to a file type. Since my files are a fairly even mix or WAV and MP3 I doubt a specific file type is suspect. Other than the crappy user interface the post 16.1 releases provide, I’ve not had any issues with the Port since I bought it. 

I have the same issues, started last week.  One speaker stops about 20 seconds before a song ends, then another drops a few seconds after that, then another….  Just one more problem with Sonos.

Sorry to hear that but it’s nice to know that I’m not crazy. I really think that Sonos’ quality control staff is failing to do their job based on the fact that 6 months after a disastrous app release they still don’t really have a working app and their legacy systems are failing.
