Over the last 6 - 9 months we have seen this issue intermittently.
- From Sonos Controller search for artist on Spotify (has also happened starting music from Spotify app - we have a paid subscription)
- choose artist
- select either Artist radio or an album by the artist or top tracks of artist
RESULTS: time bar in Sonos Controller shows the song is playing, but no sound is coming out of speakers. About 8 - 15 seconds (as per the time bar) audio comes out of the speakers at that point in the song. To be clear, there is not a delay in the start of the song, the audio starts 8 - 15 seconds into the song. Example, Bob Dylan’s Hurricane start playing audio at the words “Valentine from the upper hall”
