howto change default sound card

[Gerhard Magnus]

I'm running FC5 with two soundcards.  Here's the contents of
the /proc/asound/cards file:

0 [AudioPCI       ]: ENS1371 - Ensoniq AudioPCI
                      Ensoniq AudioPCI ENS1371 at 0xd800, irq 9
1 [DAC            ]: USB-Audio - stereo-link 1200 USB DAC
                      stereo-link stereo-link 1200 USB DAC at
usb-0000:03:0d.1-1, full speed

I would like to change the default from 0 (AudioPCI) to 1 (DAC) so I
don't have to do this manually from Kmix each time I log on.  I'm
hesistant to just alter this "cards" file as there are "card0" and
"card1" directories at the same level.  Any suggestions?  Thanks for the
help!  --Jerry
