SA:MP Launching Error

[Mircea_Niko]

In the time Argonath was down, I decided to play on other server*I will not mention it there*. I got bored, so I /q, to check if Argonath was back up - so it was. I tried to enter the server, but few secs after - Grand Theft Auto SA cannot find your audio card installed.
The audio card is installed, and works perfectly. It worked so while I was playing on the other server. What is the problem??
