I had the same problems on my brand new 12" iBook, i.e.: - modprobing dmasound_pmac fails with "No such device" - snd_powermac results in sound on headphones, no sound in speakers and an ineffective mixer Those results were seen on a vanilla 2.6.13 kernel, so my scenario looks pretty similar to yours. ;) Reading through latest kernel-changes, I got inspired by: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=821690cdc82e4090ef6f91947f76a231fad5cbb1 Unfortunately that patch didn't help, but I modified it to exactly match my soundcard-model. So, here it is: --- linux-2.6.13/sound/ppc/pmac.c 2005-08-29 14:11:45.000000000 +0200 +++ linux-2.6.13.patched/sound/ppc/pmac.c 2005-09-15 19:57:16.000000000 +0200 @@ -988,6 +988,7 @@ static int __init snd_pmac_detect(pmac_t case 0x33: case 0x29: case 0x24: + case 0x50: chip->num_freqs = ARRAY_SIZE(tumbler_freqs); chip->model = PMAC_SNAPPER; chip->can_byte_swap = 0; /* FIXME: check this */ This patch gives me sound on speakers and headphones and a lot of working mixer-controls, so it looks good...
