This is fine if you have a later ppc.
For older machines you need snd_powermac
Using the links below I got my sound fixed!

The sound module needed for differing Powerpc machines:
snd-powermac is used to run on:
AWACS, DACA, Burgundy, Tumbler, Keywest
snd_aoa_codec_onyx is used to run on:
latest (last) generation of Apple PPC
snd_aoa_tas is uded to run on:
iBooks and PowerBooks without digital
snd_aoa_codec_toonie is used to run on:
Mac Mini
See which sound module is being used:
$ cat /proc/asound/version
If its the wrong one for your machine remove the module
I tried as root
# rmmod snd_aoa_i2sbus
# rmmod snd_aoa_fabric_layout
# rmmod snd_aoa_soundbus
and
# modprobe -r snd-aoa-i2sbus snd-aoa-soundbus snd-aoa
But as they were being used I couldn't remove the modules.
So I added them to the /etc/modprobe.d/alsa-base-blacklist.conf
# Uncomment these entries in order to blacklist unwanted modem drivers
blacklist snd-atiixp-modem
blacklist snd-intel8x0m
blacklist snd-via82xx-modem
blacklist snd-pcsp
blacklist snd_aoa_i2sbus
blacklist snd_aoa_fabric_layout
blacklist snd_aoa_soundbus
8<-------8<-------8<-------8<
Then reboot: and add the sound module for your machine. For me it was:
# shutdown -r now
# modprobe snd-powermac
still no sound?
# echo snd-powermac >> /etc/modules
# shutdown -r now
Since the alsaconfig command is no longer used run:
# alsactl init
Unknown hardware: "PMac Tumbler" "PowerMac Tumbler" "" "" ""
Hardware is initialized using a guess method
$ cat /proc/asound/cards
0 [Tumbler ]: PMac Tumbler - PowerMac Tumbler
PowerMac Tumbler (Dev 14) Sub-frame 0
Yes. The correct sound module showed up.
Still no sound???
Wiggle the cable in the audio port :)
Success \0/
As I had a bad cable connection I'm not exactly sure a which point I got my sound back. I've just listed the steps I took.
