Yes, you can change the default sound chip/card in PulseAudio.  You'll 
need to redo this every time you reboot.

However, that didn't solve my problems with applications using 
PulseAudio under Fedora 9.  For some reason which I don't understand, 
the applications were not picking up on my changed PulseAudio default. 
  I then tried to find which configuration files I could change in 
PulseAudio to make my selected sound chip/card/device the default so 
that all sound applications would use it, as you can do with ALSA.

I was never successful.  And I was never able to find good 
documentation telling me how to change the configuration files in 
PulseAudio.  After a month of trying, I said 'to hell with it' and 
disabled my motherboard sound chip.  That solved my problems.

If you know how to tell PulseAudio what order of sound 
card/chip/devices to use and have PulseAudio pass this on to sound 
applications, please tell me.  But don't tell me changing the default 
by right mouse click in that one applet (sorry, I can't tell you now 
which applet that is because I've removed PulseAudio from my system) 
works-- it didn't work for my vanilla Fedora 9 system with PlanetCCRMA 
applications.  I wasn't even running a real time kernel.
