I'm running Crossover on Fedora 20, and I can't seem to get any audio from Neverwinter Nights 2. The game runs great, graphically. Amazingly, faster than on Windows, which shocked me. But I can't seem to get the audio working. I will admit that it didn't install .NET framework 3.5 when I installed the game, but I can't seem to get that to install, which was the reason it didn't install when I installed the game.
