[Florian Reitmeir <fr@3node.com>]

Hi,

i just wonderd about alle the mixer controls of my iBook G4.

there is:

Headphon
Bass
Trebele
PCM
PCM 1
PC Speak
Auto Mute
Beep
DRC
DRC Rang
Monitor

some are clear, others not. i just searched with google for a while and
controllers like 'DRC'/'DRC Rang'/'Monitor' didn't show up with some useful
explanation. Everytime i want to hear music i just try to ajust(randomly), 
and after some seconds i hear music, so is there someone how knows what all the
controllers do?
