Mic input lost

[eviljonny]

Hey,

I seem to have lost my mic input, when I unmute the mic everything seems dead, if I make a LOT of noise in the room and listen carefully I can hear it like its a long long way away and very quiet. I have checked in the windows sound and audio control panel and it is set to the correct sound input, I have also made sure the 'mic in' port isnt in use as a 5.1 port. Its also selected as the input source under the advanced settings.

At first I thought that it might be a hardware problem but today I borrowed a new sound card (Genius Soundmaker value 5.1) and exactly the same happens with this.

Specs:
Athlon XP mobile 2500+ (clocked at 2.3MHz and running cool and stable)
Abit NF7-S v1 (nForce 2 board)
2x512MB Corsair XMS RAM
Club 3D NVidia 6600GT

Anyone have any ideas how I can fix this without reinstalling windows?

Is the mic OK? Is it plugged into the mic input (not line).

The mic is tested and working on another PC and it is definitely in the mic in.
