Hi,

I have the same problem on my desktop computer. It has a integrated 
sound card on the motherboard and I have disabled it from the BIOS. The 
Ubuntu Studio however still loads the kernel modules for it and the 
symptoms are the same described above. The sound card number changes 
every time I reboot the computer.

So far I've handled the situation by manually unloading the integrated 
sound card kernel modules by issuing commands:

~$ sudo modprobe -r snd_via82xx
~$ sudo modprobe -r snd_via82xx_modem

When it comes to xmms / jack I have every time to make sure they're 
using the correct hardware device. The sound configuration in System -> 
preferences -> Sound seems not to handle two sound cards very well.

Is there any way to prevent the Ubuntu Studio loading the unwanted 
kernel modules at startup and / or get the sound cards to preserve their 
HW numbers in every boot?

Best regards:
