I'm having a similar problem. Sound used to work in Hardy Beta and stopped. I can't play any sound using Rhythmbox or mplayer (videos work without the sound). In Rhythmbox, the 'play' button can be pressed, the progress bar doesn't move. I've been keeping the system updated so it might be a breakage induced by some of the updates. I've got a 3 year old laptop with an Intel integrated AC97 based soundcard.
The strange thing is that sound input (and some output) still works: When I don't mute the integrated mic, I can hear myself clicking (mic is just next to the touchpad).
