Help with The Regiment please

While you can fix it by disabling hardware sound and EAX, the better fix is just updating your sound card drivers. Everyone that I've heard that's had this problem is running some sort of Audigy (1, 2, or 4). I had the problem myself.

Creative Labs released a new driver at the end of January and the game works fine in hardware mode using that.

Most people tend to forget about updating sound drivers since in most cases they make little difference and driver versions aren't released often. In this case, it makes a difference.
