My pc was working fine last night, I installed a windows update and shut it down, now I have no sound.
Here is the error I get
Just after a boot its fine, I go to windows sounds and test them and the audio is working, but if I try to do anything else like play an MP3 in wmp or winamp and all I get is this error.
Any ideas?
I un-installed the creative drivers and re-installed them but its still the same.
Sound card is an Xfi Fatality.
Edit - I get the same error when I try to play cod4.
