[arch-ports] [ppc]no sound after kernel upgrade

[Armin Luntzer]

Try adding snd-aoa to your rc.conf modules array, this always worked for
me. Running alsaconf isn't necessary/working at all, because it selects
snd-powermac as the kernel module.


my iBook (12"):

└> cat /proc/cpuinfo

I don't get any audio device listed from lspci/lsusb, so I guess there's
nothing to worry about that. I have no idea if this is because of a
missing entry in the device db or just something special with this type
of machines.
