I bought some Sonos speakers last week and since that I encounter a strange issue I can’t figure out what causes it and how to make it stop.

For the record, I use Spotify as music streaming service.

The issue I have is that when I start to stream music in my car or phone it automatically changes to the speakers in my home. I’ve grouped 3 of the speakers as one group and one is separate. It always transfers the music to the grouped speakers. The odd thing is that I get the music to right unit, like when I’m in my car driving but after a couple of minutes it transfers the music to the speakers at home. If I redirect it back to the car it works fine, for a couple of minutes then it transfers it back to the speakers at home again.

I never had this issue before and this started to happen as soon as I bought my Sonos speakers.
