First of all, make sure you have the sound turned on, should be in the top panel, click right on the speaker icon, and choose "Sounds Preferences". Make sure you got the output volume higher as 0% obviously, also make sure you have a working audio device, I have mine on 5.1 surround output, but this might not work for a normal onboard audio card, so make sure you choose "Stereo output".

If this didn't work there has to be a codec problem. A very easy way to install sound and video codecs if the package ubuntu-restricted-extras.

You install it using this command

sudo apt-get install ubuntu-restricted-extras

If it worked on 9.04 but not in 9.10 check that you are booting from the kernel included in 9.10: vmlinux-2.6.31-14-generic and not the one from 9.04 vmlinux-2.6.28-16-generic. This can happen if you clicked off a dialog asking you to update grub's menu.lst during installation.
