Yes, you can change the default sound chip/card in PulseAudio. You'll

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.
Best,

From this (disabling the motherboard sound chip)
I inferred that
PulseAudio was developed as a means for helping Windows users transfer
to Linux in a painless manner. I'm assuming PulseAudio was never
intended to be useful for advanced Linux audio users, because it
wasn't checking for additional sound chips/cards/devices *and*
allowing the user to specify the order in which those sound
chips/cards/devices would be used. PulseAudio always defaulted to the
motherboard sound chip, and a fair number of Linux sound applications
always default to the default sound chip/card/device (which in the
case of PulseAudio will be the motherboard sound chip.) Hence, you're
having all this trouble in trying to use a special video/audio card
because PulseAudio and very likely your sound application are only
trying to use your motherboard sound chip, since that is the default.
Hope this helps,
Stephen.
This is just wrong. You can change the default card easily from the
pulseaudio applet, see a recent thread for details and discussion. I'm
beginning to suspect that the bad acceptance of Pulseaudio that's
perceivable at least on this list is in not a small part only due to bad
user interface design. Namely hiding major functionality in context
menus in obscure places.
