When I plug my external mic in, sound settings recognizes the switch, however when I try to record anything or use skype all I hear is audio from the built-in mic just being played.
I have tried turning down the volume of the internal mic in alsamixer but that didn't really work.
The mic plugs in via audio input jack BTW.
My internal mic is unusable as it is right next to my fan and my fan is extremely noisy.
Please help if you can.
