i got a problem with my onboard mic. it is disturbing my mates when i'm talking to them via skype 'cause the fan is too close and makes annoying sounds. i tried to use an external mic but the system doesnt recognize it!!! how can i disable my onboard mic to use my external one???
Switching to an external mic is done mechanically, at the mic jack. When an external mic is plugged in, the contacts routing the signal from the internal mic are opened, and only the external mic is connected to the sound card.
If the external mic is a PC type and has a mono plug, it should work.
