look in system->preferences->soundlooks cool. Now I just got to get the sound working on Flash in Ubuntu. Oh why did I re-install?

if that's all working, it's probably a locking thing. on my 8.04 thinkpad it seems that i can only have one application producing audio at a time. i don't have time to mess around these days, so my solution is to fixing problems is to wait till they get fixed with an update/upgrade. the same reason i haven't done any of these for the last 4-5 months - no time to mess around and not enough harddrive space to just accept the updates.
