Dear all

sound output is not working on my PowerBook G4 with Debian Etch. During boot I can see a message flashing by, saying something along the lines that snd_powermac encountered an error -12. Any hints or ideas?

Hi again,

It would be better to know the exact message. Try

dmesg | grep snd

right after boot.

dmesg | grep snd
snd-aoa-fabric-layout: found bus with layout 82
snd-aoa-fabric-layout: Using PMF GPIOs
snd-aoa-codec-onyx: found pcm3052
snd-aoa-fabric-layout: can use this codec
snd-aoa-codec-onyx: attached to onyx codec via i2c
snd-aoa-codec-onyx: created and attached onyx instance
snd_powermac: probe of snd_powermac failed with error -12

Also post the output of:

lsmod | grep snd

lspci | egrep -i 'audio|media|sound'

This does not give any output, so here's the full result from lspci alone (without th egrep):
