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. -Armin Am Dienstag, den 28.08.2007, 22:31 +0200 schrieb Markus Wolf:

Hi folks,

About a couple of weeks ago, after a kernel upgrade (everything smooth as usual) the sound card of my 12" iBook stopped working. This sort of things happens sometimes, eheh everybody makes mistakes right? So I thought the issue would be resolved gracefully (i.e. with no complaints at all) within a few days with a new upgrade. But after two more upgrades, as of kernel 2.6.22 I can still hear no sound at all... I think the soundcard works, because I can hear the apple chord when I turn the machine on. alsaconf seems to recognize it properly but alsamixer tells me "No mixer elems found" and my /etc/asound.state reads like this:

state.SoundByLayout { control { } }

somewhat weird, isn't it? Furthermore lspci shows no trace of an audio card and dmesg informs me that module snd-powermac is no longer the right one, and that I should use snd-aoa, of which alsaconf seems to know nothing about... Nobody in the list has complained about this so far, either: (a) I do upgrade way too often, (b) something is wrong with my machine and I don't know what it is (c) both :( Any clues?
