/dev/dsp

[Murry Brown]

Go easy on me , I'm new. (linux only)
I am running Ubuntu 7.10, I have 2 soundcards, one onboard AC97 and a 
PCI Ensonique (soundblaster)
One is designated /dev/dsp and the other is /dev/dsp1. Normal
If I shutdown and restart or reboot the computer the cards will swap 
designations.
Eg. the AC97 was /dev/dsp and will now be /dev/dsp1 and the PCI card 
does likewise, it would go from /dev/dsp1 to /dev/dsp.
I have to go through my Amateur Radio software and keep changing 
soundcard selections.
How can I stop this?
Thanks.
