Multimedia :: sound too quiet

Hello,

listening to online radio, I have to crank up the speakers so much, that I pick up some inteference (creaky noise) from my
(optical sweek) mouse (when moved). I wonder:
where can I increase the volume on the computer other than in xmms (100%) and on the external speaker amp?
Where comes the squeaky mouse noise from?

DSL is absolutely smashing for to resussitate old doorstopper computers.
Thanks!

DSL comes with a gui application called wmix, which resides in the Fluxbox slit in a default DSL setup. It consists of a balance slider, volume knob, and arrows to choose which levels to control.
