hello, im running windows server 2003 and i have a soundcard installed on my server, that was on my MSI motherboard. and AC97 it's called, the drivers are installed and so on but when i try to play audio files trou any radiobroadcasting system or windows media player it's saying the sound device is not working properly, also i noted i can unmute sounds on the server and i wonder why this is? the soundcard is working and im using the right drivers.
