My computer seems to be refusing to play any sound files or video files. This means games are silent, and I can't listen to music on iTunes, Windows Media Player, Winamp or various other media players. I also can't watch videos stored on my computer. This happened when I downloaded the latest version of iTunes a few months ago. Whenever I try to play a sound file, it says it's playing it but the progress bar doesn't move and no sound comes out. The same happens with videos.
I've tried reinstalling the old version and about a million other things including re-downloading my sound driver, but nothing works. The funny thing is, I can play audio files in Audacity (an open source audio editor) and watch video clips (with no sound) in VLC Media Player (an open source video player). It seems like only open source things are working, could be a co-incidence though. Please, if anyone knows how to fix this, please let me know :)

umm how about you look at the mixer settings in windows. since windows 7 and vista changed how the audio actually works.
you can right click on the speaker icon and select PLAYBACK devices. I bet you have it set to headphones that are not plugged in or another device instead of your speakers. It can happen when you forget that windows doesn't change to speakers when you disconnect headphone for example.
I don't know of virus crap or maleware that will turn off your sound. check the settings first.
