I have a Vivid11 PX6 device, with android 11.
When I start the head unit and my wife is playing Spotify on another car via Android Auto (not sure is relevant), audio source on my PX6 switches to spotify (without playing music, playback device remains my wife's smartphone).
So I see spotify "playing song title", I don't hear the song (ok) and if I switch my PX6 audio source back to radio it stays with radio and play music for a bunch of seconds and then switches again to Spotify.
My PX6 is connected to my smartphone hotspot.
I want to avoid PX6 to decide on it self which audio source I use.
