There's a problem he and some people have where the audio slowly gets behind the video as you play. I don't have even the beginning of an explanation for that.
Thanks for explaining. It wasn't clear from his posts what the nature of the "desync" was exactly. My first guess would be that he might have his audio device's playback sample rate set to something non-standard.
Samurai, can you please let us know what sound device you have, what version of the driver is installed for it, and how you have it configured? Thanks.
