Microphone Problem alc272x going crazy

[Fibroga]

Hello guys, I'm writing because I have a problem that is driving me crazy.

 

I have a laptop with sound card brand PackardBell alc272x.

Then, after many tests I was able to get everything working, except for the microphone.

Use VoodooHDA 2.2 audio is good but the microphone does not want to work.

But if it does attack a USB microphone.

I tried all versions vodoohda, and the only ones that run the speakers are 2.1 and 2.2, the other or send the computer in kernel panic or feel an annoying whistle coming from the speakers.

I hope I can help, I really need the microphone but I do not want to leave this fantastic project.

10.7.3 Using Lion,

 

I3 intel processor, Nvidia Geforce GT320M, 4gb ram.

Thanks to all.
