I have absolutely no sound

[Relict]

I just installed Spacer's Choice on PC for the first time, and started it up only to find I had absolutely no audio. Every other game I've got installed, the audio works fine.

 

I tried updating my drivers. Checked my version of DirectX. Verified the integrity of the game cache. I installed the game on a different system, and, still, no sound! I can't believe I'm the only one having this problem. I'm well above the minimum requirements on both systems. Anyone have any ideas?
