Sound in iBook

[Alexander Dryakhlov]

I just installed Woody on my blueberry iBook. I'm just having problems with the 
sound. Well, it's nonexistent under Linux. And when KDE starts, for example, it 
reports that it will be sending the sound output to nill device. 
Could someone recommend a "working" configuration for this particular type of 
machine?
Thank you
