maybe it could help you:
(INSIDE THE ALSAMIXER, ALL CHANGES ARE ONLINE)
push "m" in any control with "MM" (mute)
push "up" for make grow the volume
when all looks well push "Esc"
alsactl store 0
then any time you write "alsactl restore 0" your sound configuration will be restore... but only if you have installed the bt (obviously)... later you can cat this line "alsactl restore 0" to your file /etc/rc.d/rc.local to have configured it pemanently...
good luck, young padawan
