Hi @Koze.

Thanks for sharing this! Do you happen to know if you can just lower the systemMusicPlayer but not the whole device volume? These two keys are affecting the whole system volume

Maybe there's a magic key hidden somewhere ;)

Cheerios,

I think that the volume of systemMusicPlayer is equivalent to device volume like Music app.
Therefore, there will be no API for control only the volume of the music.
