I have all the latest drivers. I even reintalled SWBF2 and my soundcard, but the same thing happens, sometimes when the sound it's set to hardware I can start on multiplayer game, but in the next it's the same error. Everytime I tried with software render sound, I get the error. ANd everytime I try with soudn disabled I can play multiplayer.
I don't know what it is, but it's defenetly sound related. But I've tried everything, and I still can't play multiplayer with sound except like 1% of the time.
