I've done it. I've bought Redguard. And yet, no matter which one I follow, I cannot get the game to run with sound. I tried both guides, DOSBox and Windows XP guides. The DOSBox one actually had a fatal error and couldn't even RUN.

The other method gets the game up and running, but it just doesn't give me any sound. I followed it closely, but no sound.

Have you tried to play it with glidos? I can play redguard with sound but no music

Can't pay for Glidos right now...

That's the only way to get Redguard running with sound
