Hi, I've been using my PowerMac G5 for audio recording with a pro tools rig for a while and just recently decided I'd try some games out on it. I downloaded the new myst game and there no audio. I downloaded Doom 3 and no audio. And Americas army no audio. I've tried with the digicore turned on, and the digi core turned off so that the internal sound card would play, but nothing. Every other application sound works fine, itunes, real player, websites. Is there something I need to turn on for the sound to work with these games?
