you can try changing the sound buffer size to 512 or something then restarting the game
15:19
the sound appears a little off sync with the video but there's no big ridiculous duration of 6 hoursthe offsync issue is what i get for not testing the video with VLC instead of windows media player/MPC-HC...
i rendered another video and it played just fine on the last two mentioned players, nevermind(edited)
