Windows 7 - Microphone not wroking[Realtek issues]

Hey,new here, anyway here is my problem : I recently bought a new computer, got windows 7 ultimate, everything worked so fine xD till i got to try the microphone...seems like i have an ALC 889 Realtek HD integrated audio, and the funny thing is that it reads my microphone but no sound, only sometimes for 1 sec it works, then goes "dead" again, i have the latest drivers from realtek, and i tried 4 different microphones on jack 3.1 , anyway usb microphones are working.. but can anyone help me with this problem.. ? thanks in advance

Have you tested your problem on different software?

you mean like on another driver ? neah if you have any other driver that i can test just give me the name really don't know what other driver to use.. anyway if you mean programs...it doesn't work in any program.. only for one sec at 10 minutes or something like that
