I have been having trouble playing the game. When I arrive just outside the gates of New Tristram, the game locks up and then loses sound, then becomes playable again but without sound.
I'm outputting my sound via HDMI through my graphics card, and running the game at 1920x1080 resolution, fullscreen.
My specs are as follows:
CPU: Intel Core i7 3930K @3.2GHz (stock speed)
Mainboard: AsRock X79 Extreme9
RAM: 16GB G.Skillz Ripjaws Z
Video Card: Nvidia GeForce GTX 680
OS: Microsoft Windows 7 Professional 64bit
