Could you include an option in amixer to save and
restore all the mixer controls for a given card?
This could help to set up all controls to a default
value after reboot.
Think about SBLive. It has a lot of controls with some
setting for each one.
Ideal state should be saved.
-s =>>> get and save
-r =>>> restore
amixer -s emu10k1-alsa.config -c 1
amixer -r emu10k1-alsa.config -c 1
This would help a lot.
