OK, so after scouring Google in vain, I thought I might try here about a strange problem which has cropped up.
I'm using Win XP, and suddenly, no video file of any type, using any player will output sound anymore! Audio by itself works just fine using only foobar to play mp3, FLAC etc, but I don't get any sound output when playing any audio or video files using Windows Media Player, Winamp, MPC, DivX player etc.

IM client ping sounds don't work either, and nor does audio for YouTube etc.

I tried switching to the other soundcard on my PC, but no dice. This is bizarre. Any idea what could be wrong?

Don't want to ask the obvious but sound isn't muted? Is the correct device selected? (control panel > sound and audio devices > audio).

Checked that already. Tried everything, including downloading codecs...
