I've got what I think is a bug. I'm running the game on a fully updated version of Windows 7 Enterprise and when I start it up I get an error message telling me Direct Sound won't initialise and asking me to close any programs that might be running in the background.
I've closed everything I can think of that that could concievably be interfering with Direct Sound and its made no differnce. Any ideas?
This may be a long shot, but you could try to restart your Audio Service.
Either in the service overview (services.msc), in which it is called "Windows-Audio" in my German Win7 installation, or via an elevated command line prompt (elevated meaning with admin rights), by typing "stop AudioSrv" and then "start AudioSrv".
