sargo/bonito: There should be a way to change call audio volume using the buttons and use Bluetooth for calls

Currently the audio volume has to be set like this for calls:

amixer -c 0 cset name='Top Digital PCM Volume' 60% # Earpiece
amixer -c 0 cset name='Bottom Digital PCM Volume' 60% # Speaker
amixer -c 0 cset name='Digital RX1 Digital Volume' 60% # Headphones Left
amixer -c 0 cset name='Digital RX2 Digital Volume' 60% # Headphones Right
alsactl store # Make this configuration persist across reboots

Taken from the pmOS wiki. They recommend 23 %, but I could no longer get any audio at all while at 23 %.

There should be a way to change the volume using the buttons on the side. 🤔

Any ideas for that?

Also, switching to Bluetooth should make calls work via Bluetooth at some point, but I guess that would require a complete rewrite of q6voiced.
