RockPro64 line out/headphones in Android 9
Ok, so it seems that line out/headphones jack works in Android 9 on RockPro, but I need to run this app before:
Without running it and clicking on Speaker Toggle there is no audio from audio jack. It seems that the headphones/line out cable is not detected.

So, how do I enable line out by default after boot? Now I have to run that Speaker Toggle after each boot when I want to use line out.

there must be some asound/alsa config some somewhere, but I was unable to find it.

I found this app better for that
It allows running after start and it can automatically set the desired output (although the outputs are reversed).
