Yes. There it works. (Tested with doom and xmame and "cat xxx >

PowerMac (AWACS rev 100) DMA sound driver rev 016 :
Core driver edition 01.01 : Built-in Sound driver edition 00.01
sound.format = 0x8 (unsigned 8 bit)
sound.speed = 8000Hz (phys. 44100Hz)
sound.stereo = 0x0 (mono)
sq.block_size = 32768 sq.max_count = 4 sq.max_active = 4
sq.count = 0 sq.rear_size = 9568
sq.active = 0 sq.syncing = 0
How do I know whether I have the "burgundy" sound chip?

I will do tomorrow (it's late by now)

I thought of this myself, but I installed some mixer programs and xmcd
and set the level to full in all of them. No avail. xmcd starts the CD
but nothing comes out of the speakers.
