Problema configuration audio system


I am new using open suse, and I have problems with my system audio, I can heard the audio system, but I can set up the volumen, if I try to up the volumen, the system show me, that I am setting my volumen up and down, but I heard it at the same level, the same happens if I set up and down the volumen with kmix.
I thing is my driver, how can I upgrade my driver, or set it.?
Can you help me with this?
I have via audio card vt 82327 built in, on asrock mother board.

Thanks in advanced,

Right click kmix and choose Select Master Channel. Choose Master instead of PCM or viceversa
