Whenever i connect in multiplayer to a server, it goes KRSH KRSH KRSH KRSH KRSH and then all sound in & out of game dies. Then i see this in console:
Couldn’t get sound buffer status
Couldn’t get sound buffer status
Couldn’t get sound buffer status
Couldn’t get sound buffer status
Couldn’t get sound buffer status
Couldn’t get sound buffer status
It says the best drives for the codec and the ati function is good, what is it?

My friend says it may be that i have Win 7 32 bit, can anyone shine some light on this?
