Sound problem

Sound problem

I have this problem when i run warcraft it writes in game:
"Unable to initalize base sound services, sound is disabled"

In other games sound is disabled too.
But in winamp music still works.

Please tell me whats the problem an what to do

... Honestly... I'd save my money and buy new speakers, new wc3 and wac3 tft, and if non of this works, over time just save money for a new comp

maybe my something happened with my audio card
Or driver.

Re-install audio driver, test if it works fine using another audio card (if you're able to get one).
