yup.. that's the problem. I bind a key for it to restart the sound whenever it does in surround mode but it happen too frequent so.. no choice but to play in stereo mode with CMSS on. Sighz..wachtourak said:When it does it I just go into options and switch to stereo then back to surround and it fixes it. Happens very rarely. I'm running onboard Nvida Nforce 2 Soundstorm sound by the way...
