It may be you need to configure alsa to load the other soundcard. Have you 
tried this from Ubuntu Forums on multiple soundcards:

In a shell, type cat /proc/asound/modules

I have onboard Nvidia and a soundblaster soundcard and I get this

0 snd_emu10k1
1 snd_mpu401
2 snd_intel8x0

This will give the the name and index of each soundcard you have currently. 
Make a note of the names, and decide which one you want to be the default 
Now type 
sudo nano /etc/modprobe.d/alsa-base

At the very end of the file, add the following (assuming you have 3 cards with 
module names A, B and C and you want to have them in the order CAB)

options snd-C index=0
options snd-A index=1
options snd-B index=2

The emu10k1 is the one I want to load so the last few lines of my alsa-base 
looks like this: 

# Ubuntu #62691, enable MPU for snd-cmipci
options snd-cmipci mpu_port=0x330 fm_port=0x388
options snd-snd_emu10k1 index=-0
options snd-snd_mpu401 index=-1
options snd-intel8x0 index=-2

If you are still having problems with the wrong soundcard loading you may be 
running Edgy. Try upgrading to Fesity. I found that in Edgy even with this 
setup I had to reboot 4 or more times until it picked up the right soundcard.
