Summary:                    Sound is not working on the MacMini
Description: 
Sound is not working on the MacMini. When loading the dmasound_pmac i get
the following error:

FATAL: Error inserting dmasound_pmac
(/lib/modules/2.6.11.5/kernel/sound/oss/dmasound/dmasound_pmac.ko): No
such device

When trying to play music i get an "maybe your device is busy?" error.

I've found a solution on the ubuntuforums(
http://www.ubuntuforums.org/showthread.php?t=12748 )

it says:

To manually apply the patch (just as easy in this case),
just open the file linux/sound/ppc/pmac.c in an editor,
and search for OAKeylargo.
Where it says SNAPPER right below, you change to SCREAMER (in uppercase).
(In kernel 2.6.10 it's at line 967). 

this solution is very minimal, the alsamixer is slow, and my computer
hangs for a couple of seconds before the start of every new process (when
opening a new window in gnome etc.). When i edit pmac.c in the old way my
system runs normal again.

What do i need to do to check it?
I've never hacked in a module. i don't even know exactly what module i
need to load.
or is there some logfile?

no, it's not a screamer. It's an awacs, I am running a kernel with the
change above, but set to AWACS, and sound works perfectly.
