Those are the new G4s. They use yet a new audio chip which is on the I2S/
I2C bus (and also use various GPIOs for things like speaker mute). I
don't have much more details yet.
I don't think there is anything related between the sound chip and the
Adaptec card. Those old problems were possibly due to some bus bandwidth
problems & DBDMA bugs, I don't think KeyLargo is subject to such bugs.
Ben.
