Gaps when playing playlists

Hello, I have downgraded my 4 sonos play 3 to S1. When on S2 there were constant dropouts. I do not have the dropouts more, but gaps when playing a playlist. It is the playlist I have created, playlists from Roon or Tidal. There is several seconds of breake between songs. If I skip in the midden of a track, no issues. I have tried other endpoints, there are no problems with them.
Anny good suggestions?
