[newbie] two sound cards

[Anthony C. Cheng]

I have two sound cards installed, one pci and one on the motherboard.  I'd
like to use the pci sound card.  Most of the programs, however, are using
the one built on the motherboard.  How do I set the pci card to be the
default sound device?  Also, what is the difference between /dev/audio and
/dev/dps?
