Problem with sound card/application

[xRoNx]

I have an Intel AC'97 audio controller on my laptop. The problem is, my system has no sound at all, and when i boot up GNOME, i get this 3 error messages:

1) The application "Mixer_applet2" has quit unexpectedly

2) The panel encountered a problem while loading "OAFIID:GNOME_MixerApplet" Details:Unknown CORBA exception id: 'IDL:omg.org/CORBA/comm_FAILURE:1.0'

3) The "Volume Control" applet appears to have died unexpectedly.

My lsmod returned this output:
