Hi Community!

Alright, ALSA Works perfectly. But I have NO Microphone...dont even see a slider in alsamixer.

Ok here is what I use:

Kernel: 2.6.7-gentoo-r11
alsa-utils 1.0.5
alsa-oss 1.0.5
alsa-driver: not installed...using kernel modules only

Here are my loaded Modules
Code:

Module                  Size  Used by
snd_pcm_oss            64584  1
snd_mixer_oss          22144  2 snd_pcm_oss
i2c_keywest            11396  0
snd_powermac           42800  2

soundcore              11428  3 snd


Here is my amixer output

The Microphone in an iBook 600 will not work. The code for it has not been written yet.

Even in newer iBooks the mic is accessible, but would not record any good sound.
