I think that a good start would be a kernel uptate! Put the vanilla-sources-2.6.13.5
!!!

Try to run "alsamixer", and put the "Input So" to "mic".

It already is. What I don't know is if the internal microphone of the iBook G4 1.2 GHz is supported under GNU/Linux.

Strange... I have a powerbook G4 aluminium, and it works... I don't think this hw is too different..

Ah! Does an external microphone works? :?

Unfortunately this iBook doesn't have a line-in entrance, so it only allows USB microphones, which I don't have. I've been wandering through some forums and I never seen any sucess stories on this one. But, then again, all the information I could get was outdated by a year, at least.

My book supports the microphone as far as I now. I didn't use a recording software. But if I increase the mic volume, I get a feedback trough the speakers:)
My goal is using linphone .

Maybe only an alsamixer switch is missing? Who is responsible for this? The alsa project?

It is well supported on my ibook g4 1.2Ghz 12" (using audacity).

Sorry, I don't understand your question.
(Maybe audacity ? It's a software I use for recording sound)

That is great news! Do you use ALSA or OSS? And do you use something like esd or arts for sound input?

I use ALSA and its OSS emulation, and don't use esd and arts (I don't need them because I use FVWM).

In alsamixer I can chose mic as input and move the monitor slider until feedback :) There is also PCM1 but it's not used for microphone here. PCM and PCM1 are set to maximum. How could I easily test the microphone? I only test it with linphone now.

If you're using GNOME, you can use GNOME's Sound Recorder.

Which, by the way, seems to be broken... that's the main reason I though my mic wasn't working. I've emerged sox and tried the rec program and it worked out great. Thanks everyone for your comments, which led me to this great discovery. :D

Wow, that microphone really works well. I did not know. But now how can I change the input volume. I tried every slide of alsamixer and I think the one for microphone volume is just missing there.
