That info is not enough to identify your hardware properly :-)

Run these command and put here the ouput:

cat /proc/asound/cards
head -n 1 /proc/asound/card0/codec*

It can be that sound card is not being properly detected and you need to pass 
the "model=" parameter to the ALSA config file. Depending on the codec and your 
kernel verion, you can edit the alsa configuration file and append to the
"options" line a value that matches with your sound card hardware settings:

http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt

It can also be that your sound card chipset is too new for your kernel or alsa 
version but that would be strange given that your're on wheezy. Was the mic 
detected before or has never worked?
