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. ** Sent via the linuxppc-dev mail list.
