I installed the BioShock Demo on Windows Vista 64-bit. There is a known problem where the sound stops working after the plane crashes in the opening scene. I managed to gain audio by setting the shortcut to Windows Server 2003 compatability mode. For some reason I have to turn off the compatability mode to change settings though, and when I enable v-sync it disables itself as soon as I go back into compatability mode. What should I do? Right now I must choose between v-sync and audio... is this fixed in the full game? Is it because I'm trying to play in DirectX 10 under Server 2003 mode?
