Hello

I'm using unbuntu 11.04, with kde. using ALSA for sound

the problem is that my internal microphone on the laptop isn't working. however, I can hear the microphone real time in my headphones. I have everything in alsamixer unmuted, but I can't figure out why it's not receiving the microphone as the main input.

checked sound recorder, and people can't hear me in mangler/vent on wine.

help much appreciated :D

Hmm.. Maybe a wine application is not the best one for a sound check! :)

Anyway, just in case, can you open a terminal, start alsamixer,
then press tab (to go to the "capture" settings), then go to "Mic" and then try the up and down arrows? You should probably get something like "internal mic".. Try to experiment with this,
you may get the appropriate input in the end..

If you can hear mic input then the capture settings are probably at issue. Post your amixer output:
