Different programs using different sound card

[kortez]

Apparently different programs like to use different sound cards for audio, either the pci card or the on board card. Here is a list of some programs and what card they use:
On board
-vlc
-rhythm box
-pidgin
-post login sound
PCI
-firefox
-hydrogen
-ubuntu sounds (pre-login drums, hardware testing, so far i have found)
Is there a way to make a program use a certain sound card? It is quite annoying when I have to switch what my speakers are hooked up to frequently.
Thank you in advance for help.

If you disable your onboard sound card in the BIOS you won't have this problem.
