Changing primary sound card or disabling a sound card
 

Since I installed Ubuntu Linux, I have had a problem with the wrong sound card being the primary sound device. I have two sound cards, a Terratec card (the one that I mainly use) and an old Soundblaster that I only use for old games in Windows.

I have searched around, both on this forum and the Ubuntu support forum, and found a couple of solutions for either changing primary sound card or disabling a sound card. (it doesn't matter which one, as I don't have any use for the Soundblaster card in Linux anyway) Some of them have not been possible to do, and others have either not worked at all or only worked until I rebooted. (I can fix it temporary anyway, by remaining /dev/dsp to dsp1 and /dev/dsp1 to dsp, but I want it to stay in effect)

So, does anyone have any solution that stays in effect? (again, doesn't matter whether it disables the Soundblaster or simply switches primary sound card)

this worked for me:

It works so far as to get the sound working, but dev/dsp still identifies as the soundblaster card, making it quite hard to use mixer applications. It doesn't work after rebooting however.
