I have no game sound at all. Not during cutscenes, the intro, after I load the game, nothing. Any ideas what's wrong? I just installed the games recently on a new computer.

Same thing with me. I manage to make it to the game, but no sound at all.

I sometimes have sound when it loads, sometimes not. And never the inplay sounds.

You need to install DirectX 9.0c on the system
DirectX 9.0 with Runtime Pack (June 2010)
https://www.microsoft.com/en-au/download/details.aspx?id=8109

Try, turned off "3D sound", in-game Menu =>Options =>Audio

Looping audio problem
When you have more than 2 speakers (2.1 or 5.1 or 7.1 sound)
Also, modern sound cards can work in surround sound emulation mode.
Older games don't know what surround sound is.
Download "Version 0.12", unpack and move to the game folder.

(or "Version 0.14" with EAX=off by default)
This dsound.dll replaces the native one from DirectX, like a wrapper, reconciles the old with the new.
