Yes it's possible with PulseAudio, but really the policy regarding this is left to the various Desktop Environments that use it, e.g. GNOME, KDE etc. > KDE's kmix used to support setting a "default soundcard" (however, that > didn't really work), however after I switched to XFCE I don't find any > such options - looks like I have to configure it manually. In KMix, it's really just controls which soundcard to use for the volume controls (e.g. in the system tray or via the multimedia keys on laptops and keyboards). It's nothing to do with which actual sound card you use by default for applications. In KDE you can setup the exact routing structure you want in System Settings -> Multimedia -> Phonon. http://pulseaudio.org/wiki/KDE Under GNOME you cannot do this by default (it's possible, but there would be no GUI for it!) and IIRC XFCE uses the GNOME UIs for volume control stuff. So for now, whenever you plug in your USB, you'll have to fire up the Gnome control panel and choose "Sound", then pick the device on the Output tab. Alternatively, you can use pavucontrol and select the device as your preferred fallback. Provided you don't specifically move applications to a new sink (in pavucontrol's playback tab) then the fallback will be used.
