- - mixerctl is a bit unintuitive - you did use outputs.speaker, didn't 
you?
- - are you sure your iBook actually has an awacs?

That said, please mail me your dmesg output and if at all possible 
please compile src/usr.sbin/ofctl and send me the output of ofctl -p ( 
this will dump the entire OpenFirmware device tree, including 
properties ) so I can see what hardware you have.
What could cause this might be:
- - wrong driver. Did you try snapper?
- - external mixer like on the beige G3 - ofctl -p should tell us if 
that's the case.
- - some weird bug in awacs ( don't think that's too likely though )

have fun
Michael
