No Audio after April update (10.04 - The Lucid Lynx)

Try this.

rm -r ~/.pulse ~/.asound* 
sudo rm /etc/asound.conf

Logout/in.

I just realized that a similar thing happened to me after a recent update. My sound card was still listed in the sound preferences, but I could just not get any audio output.

Deleting the ~/.pulse directory (actually, moving it to ~/.pulse.bak) and restarting pulseaudio (killall pulseaudio), got my sound back.
