Hmmm. Can you post the output of

$ lsmod | grep snd

I have an onboard Intel sound system, which works fine in Jaunty, and I
think I've had Hardy on this system as well.

I used to know how to test sound by doing something like

$ cat somefile > /dev/dsp

But I don't remember what sort of file it needs to be. I think raw audio,
but then you need to set your sound system to a particular bitrate.

However, I just tried this:

$ cat /dev/urandom > /dev/dsp

and I indeed get something resembling white noise. And my system didn't
explode either. (Just hit CTRL_C to stop.)

I think if the above doesn't result in any sound, then either there's some
setting which is off, or maybe your sound system has a hardware problem.
