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
processor : 0
cpu : 7447A, altivec supported
clock : 666.666000MHz
revision : 0.5 (pvr 8003 0105)
bogomips : 36.73
timebase : 18432000
platform : PowerMac
machine : PowerBook6,7
motherboard : PowerBook6,7 MacRISC3 Power Macintosh
detected as : 287 (iBook G4)
pmac flags : 0000001b
L2 cache : 512K unified
pmac-generation : NewWorld
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.
