The built-in mic on the eeepc (900) works fine, i.e. when it's on, you can hear that it picks up environment sound. Whenever I try to do something with it, i.e., use it in skype, it doesn't record anything (same for Gnome Sound Recorder). It is properly listed in the sound input device section of skype, and when I plugin an external mic, everything works well. Any ideas? This is important as I'll be going abroad next week, and it would be great to be able to use skype...

did you try to switch the input channel to use the camera mic?
you can do it with any mixer i.e. kmix or alsamixer.

use this to check (visual impression of) mic input



I played also a bit to get it work
