Description of problem:
On the imac 333, the soundcard isnt properly detected. I'm guessing this is similar for numerous other Mac machines.
by running a modprobe snd-powermac I was able to start the soundcard on the box, however it's worth noting that doing so also opens up the mic channel, which is close enough on this box to wind up a painful feedback loop (ouch). Should you want to try this. make sure you're already booted into X so you can quickly start the volume control app and mute the mic :D
here's an lspci for the box
00:00.0 Host bridge: Motorola MPC106 [Grackle] (rev 40)
00:10.0 Class ff00: Apple Computer Inc. Paddington Mac I/O
00:12.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro 215GP (rev 5
00:14.0 USB Controller: OPTi Inc. 82C861 (rev 10)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install fc4test2 on a ppc imac 333
2. No sound detected.
Does the feedback persits if you:
a) remove /etc/asound.state
b) move /etc/dev.d/sound/alsa.dev out of the way?
What does 'kudzu -p -b macio' say?

To tell you the truth, as soon as I muted it it went away. It was just a note I
left there for whomever fixes the detection to make sure and mute the mic if
you find the device ;)
[root@adrastea ~]# kudzu -p -b macio

Although I've now added 'alias snd-card-0 snd-powermac' to
my /etc/modprobe.conf Do you need me to undo this and restart the box for a
clean check to fix this bug?
Actually, this matches another bug.

This problem has resurfaced in Fedora 9
Assigning to kernel - kudzu is not involved with this in Fedora 9.
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
