Simulated speech isn't working in any part of the game, and I can't figure out why. I've tried setting it to play for briefings, in-mission and in the tech room in the launcher, but it doesn't work in any of them. I tried running the launcher in Administrator mode, but that didn't work either.
I tried searching through the Hard-Light forums for a solution, but the only thing potentially useful I found was an FAQ mentioning how some versions of FS2_Open don't have simulated speech functional. Is that the case for Diaspora?
