I just upgraded my system to a Gigabyte G31M-S2L motherboard and i just finished installing the latest realtek drivers, but when i try to use my mic(which i plugged into my rear pink in jack) my mic doesnt seem to respond to anything. Speakers and headphones work fine, but not the mic. When i check the audio manager it says it sees a mic is plugged in. Another weird problem is when i try master volume options and try to check the rear pink jack....i find out there is no rear pink jack in the options. BUT there is a front pink and green jack. What confuses me is i do not have a front pink or green jack on my actual pc case.

anyone have some ideas? iv looked around all over and still no fix.
