Powerbook still pops and clicks

[Brendan J Simon <brendan.simon@ctam.com.au>]

My powerbook (G3-500MHz-firewire) makes clicking and popping sounds.  
I've tried it with MacOS and with just the yaboot prompt and it 
*doesn't* click and pop.  It only makes the clicking and popping sounds 
when running Debian GNU Linux.

I'm running with kernel 2.2.17 and X-4.0.1.  I might try disabling the X 
server and see if that makes any difference.  Maybe I have to setup my 
sound system some how ???

Does anybody else have a new powerbook that makes clicking/popping 
sounds when running Debian GNU Linux ?

Does anyone know how to solve the anoying clicking/popping ???

Thanks for any help/ideas,
Brendan Simon.
