I'm not really sure what the officially recommended procedure is, but here's what works for me (Intrepid):

For pulseaudio; edit /etc/pulse/default.pa and add a line
set-default-sink nameofyoursoundcard
(where nameofyoursoundcard is something like "alsa_output.pci_1412_1724_sound_card_0_alsa_playback_0", you can find it if you use the command "pactl list").

After you have done that, delete the files under ~/.pulse , then logout and login again.
