The Beige G3's audio varies on what personality card you have. It uses
Burgundy if you have the DVD card, I think. My Pismo G3 is using Burgundy.

I have never heard of AWACS Screamer...

The iBook uses an IC called Screamer. It is an I2S controller that is run
off one of the internal serial ports (one of the reasons the iBook has no
IrDA). The newer iBooks and digitial Audio G4's use Tumbler (I have no
idea how this is interfaced).
