I'm running debian woody on a iMac 350 (slot loading) and I seem to get
problems with the sound when it is sent through the headphones socket on
the right of the machine. The sound is rough, not crackly, it's
difficult to describe but definatly wrong. I think the sound is ok
through the speaker but it is not as easy to tell. I do not have this
problem under Mac OS9 or Mac OSX. I'm using dmasound_pmac and the
standard debian kernel:
i2c-core.o: i2c core module
i2c-core.o: adapter uni-n 0 registered as adapter 0.
i2c-core.o: adapter uni-n 1 registered as adapter 1.
Found KeyWest i2c on "uni-n", 2 channels, stepping: 4 bits

dmasound_pmac: Awacs/Screamer Codec Mfct: 1 Rev 3
PowerMac Screamer DMA sound driver rev 016 installed
Core driver edition 01.06 : PowerMac Built-in Sound driver edition 00.07
Write will use 4 fragments of 32768 bytes as default
Read will use 4 fragments of 32768 bytes as default
Also is it possible to have the speakers muted when headphones are
plugged in as under Mac OS(9,X)?
Thank you for any help
