Well the main tool that is used when you have PA underneath is
pavucontrol. This app will allow you to work with all your currently
running streams and allow you to change the device they use etc. Once
you change this setting it should be remembered from then on (e.g. pulse
will know that VLC prefers to be on the Audigy, MythTV prefers the VIA etc.)
pavucontrol also let's you set the "default" sink, so that brand new
streams will go through your preferred device by default. This does not
apply to applications that have already played as they will be
remembered as perfering the device they were first played on (IMO this
is suboptimal and there should be a concept of "default" built in to the
stream remembering stuff - this will come eventually I'm sure).
VLC now has a pulse output module. I'm not sure if that is the official
version nor if it is part of the vlc package on F10, but I'd imagine so.
Also there is a patch for MythTV that adds pulse support too (I rediffed
Also in order to get pulse to do multichannel you have to set the
channels to 6 (for 5.1) in your /etc/pulse/daemon.conf (there may be a
config program to do this in F10, I'm not familiar with it - we have a
GUI in Mandriva I know that much :))
