after installing modem driver my computer freezes when sound is played! When I was dialing up to the internet I stopped playing music(paused it) to see if it was making sound then I pressed play and it froze (cant move mouse,totally nothing!)! I then restarted then connected to the internet but didn't play music at all and it worked fine... untill I started xmms and played music (complete freeze!) Then I restarted and then did internet stuff disconnected and then played music....and it worked!!!! It freezes when iI use an media player or when I enable sound server

any ideas?
I got a smart link 561 PCI modem
NForce 2 audio codec interface sound card
