Problem: I can't play any sound or music from anything.

History: Was working fine until me wifers and I went on a add/remove program
spree trying to free up some space. Now she asked me before she removed every
program and I used to be a computer tech... well three or for years ago. so
anything I didn't recongise and didn't see important to opreations of the
computer I gave the A-OK. Somehow though we managed to to remove the volume
control. Everything was working fine until the removal spree.

Question: I was wondering how I would be able to get that back without doing
anything extreme such as reinstalling windows.
