How to disable soundcard

Asked by ixez

Hello everybody!

I'm using an HP dm1-2050er laptop with Kubuntu 11.10 64-bit.
I have an IDT audio controller but there is also AMD RS880 audio controller.
Of course, I'm using IDT all the time but the sound icon in the tray shows the volume level regulator only for RS880.
How could I disable the RS880 controller in my system or switch the displayed device in the tray?

Help me, please.

Tried looking in the BIOS?

Yes and my laptops' BIOS has no such settings. It almost has a few settings :/

Can you give the output of:

sudo lshw -C sound; lsb_release -a; uname -a

Thanks

System Settings > Sound.
Click on the Hardware tab.
Select the device to configure.
Under "Settings for the selected device" use the Profile list box to choose "Off".
