Alsa trouble with headphones

[Janina Sajka]

A command like:

amixer controls

should list out the various controls associated with your audio device.
You may, of course, need to pipe this:

amixer controls |more

Once you know the device that controls your headphone volume level, you
can querry it's current setting:

amixer cget numid=X

where X is the correct number which you leareed from 'amixer controls' .
Now you can reset to a more appropriate level like this:

amixer cset numid=X YY

where YY is a volume setting you want to try. When yhou have it right,
do:

alsactl store

hth
