Hello,

It may not be the good list to post that. (?)

I am now able to play sound but have not understood how to change the
volume at which it is playing.

mixerctl -a says:

monitor.output=headphones
outputs.speaker=0,0
outputs.headphones=32,32
record.source=cd
record.record=64,64 

but changin any values with mixerctl -w does not change the hearing
volume. (too much if I plug headphones, too low if any when I do not)

audioctl -a says many things, including things about play.gain, but I
cannot set it to anything else than 127...
