Hi,
I'm using the close source app Symfonium for music playback on my Pixel 9. I wanted to try it out, because it supports many selfhosted music server protocols, offline playback and most importantly Android Auto support. Sadly I can't get it to work. When I use Android Auto, Symfonium refuses to show up (wirelessly and wired). The app developer says there is nothing he can do on his side.
I wanted to ask the GrapheneOS userbase, if anybody got it working and maybe also tell me the car model it works with. Don't forget to mention, if you got it working wirelessly or not. Thank you.
