Comment 69 for bug 141445

Hello everyone!
I'm very new to Ubuntu, I don't know much of what is written here. what I do know is that my internal microphone isn't working properly. I can only switch between two options: 1 - output works, mic doesn't
                                                                             2 - mic works, output doesn't
I change it in Sound preferences, on hardware tab, there are quite few hardware profiles, one of them gives me sound, the other gives microphone.

If some one is good in this things, please hepl!
I use Vaio AR51J Laptop.

Thank you in advance.
