I recently got a Creative Sound Blaster Omni Surround USB external sound card, and a 5.1 speaker system. Now, I have been trying this setup with various things, and when I get to Doom 3 and Quake 4, I have no audio whatsoever. It's completely mute. I've tried what I know about these games, but I can't get the sound to work. They are fine with the internal speakers, but when using the Omni Surround, nothing. They also have a weird thing where they aren't properly detecting my system specs. Doom 3 reporting it thinks I have 2GB RAM instead of 8GB, and 256MB VRAM instead of 512MB. Quake 4 reporting my RAM correctly, but again getting the VRAM wrong. How do I fix this? I really don't want to have to change the output device just to get sound in these games.
