How much did you try to change it by?
marder-1:/usr/marko{55}% mixer vol
Mixer vol is currently set to 100:100
marder-1:/usr/marko{56}% mixer vol 99
Setting the mixer vol to 99:99.
marder-1:/usr/marko{57}% mixer vol
Mixer vol is currently set to 100:100
marder-1:/usr/marko{58}% mixer vol 98
Setting the mixer vol to 98:98.
marder-1:/usr/marko{59}% mixer vol
Mixer vol is currently set to 100:100
marder-1:/usr/marko{60}% mixer vol 97
Setting the mixer vol to 97:97.
marder-1:/usr/marko{61}% mixer vol
Mixer vol is currently set to 97:97
marder-1:/usr/marko{62}%
The cause is that the soundcard only has 64 steps for the volume but
mixer(8) and the ioctl() has 100 so there is a loss of precision when
converting back and forward. I'm working on a solution.
