No sound profile

[Cedric]

My sound is recognized by ubuntu 12.04.
Sound-indicator is working well.
I am able to play sound.

I am able to play sound with my sound card ALC-861-AV, but in the gnome-control-center i am unable to select a sound profile.
There is no sound profile which i can choose. It isn't possible to test the sound or to change the volume.
