After a lot of testing, here is the current state of things:
Whats working:
- Bluetooth: I tested Bluetooth with the Twingo again and realized that you have to go into a sub-sub-sub-menu where you can switch the source to Bluetooth. Really annoying but yea, it was not the phone’s fault. Same with the PC, Gnome-Desktop messed with the Bluetooth-connection as mentioned before.
- Android Auto: I think that must have been fixed by an update, because I tried it with the Twingo (again), an Opel Corsa & AA-DHU (USB & wireless), everything is working fine now, doesn’t matter which music app I use.
- Stock music-app (in Android Auto): I noticed the issue with the crashing AA-app has been reported at aa4mg’s git (A magisk-module that implements AA into MicroG based Systems). I don’t use it and the person who reported it doesn’t use iodeOS, so I guess that was yet another bug with the stock music app that is now fixed?
What ins’t working:
-
Stock music-app (visuals): I looked up the git of this app and found this bug-report & this bug-report. The visual indicators for the playback progress are tied to the animation-speed that is set within Android-settings. Since mine is set 0.5, for each passed second the indicators move 2 seconds. This was reported over a year ago and hasn’t been fixed yet, pretty disappointing tbh.
-
Stock music-app (playback): Some songs still don’t playback unless I start a screen-recording (for whatever reason). Instead I get a infinitely circling loading bar, no meta-data gets shown and no playback is happening.
-
Rotating screen: Rotating the screen still causes audio-dropouts. Not a big issue but an issue nevertheless.
