Is it only mp3's or vid files where you get no sound, or do you not get
any sound period?

If you have no sound at all, can you post the complete output from the
following commands run in a terminal?

$ sudo hwinfo --sound
$ lsmod |grep snd

If you get a message that hwinfo isn't installed, issue the command
"sudo apt-get install hwinfo" and then run it.

If it's only with mp3's and vid files that you don't have sound, then it
may be that you don't have the necessary decoders installed. There's a
package in the multiverse repository that grabs a lot of packages that
provide mp3 playback and other stuff. If you have the multiverse
repository enabled, you can install it with Synaptic or with "sudo
apt-get install ubuntu-restricted-extras" (if you are on a slow
connection like dial-up, this will take a long time).
