Hi there,
I recently installed Kubuntu 9.10 Beta on my brothers Dell Inspiron laptop. Everything works just perfect, except for microphone. There is no built-in microphone on the notebook, so we have to use external microphone when using Skype etc. However I can't get it working. I also installed Pulse audio packages and tried to play with PulseAudio Device Chooser, but it seems it doesn't detect the microphone. I checked AlsaMixer and I put all the devices to 100% volume, but didn't help.
Here is my amixer output:
