I have Civilization III Complete for the Mac, and when I try to play the music and sound is erratic and does not work properly. Oftentimes the music will skip, repeating the same section multiple times over. It does this throughout the whole track. Can make a 4 minute track almost 10 minutes long. Diplomacy causes sound problems as well. Sometimes when I enter diplomacy the soundtrack continues to play, with both diplomusic and soundtrack playing. When I leave diplomacy, they both stop playing. I can go back in, and both restart. This means the music is nearly unusable. Sounds are also bugged. I have no combat sounds whatsoever. Some sounds work partially, but others just fail to play. I am not sure what is causing these problems, as it does this on multiple computers. I have also found that in the Conquests scenarios the sound is more unstable than a regular match. Not sure if this is really the case or just my luck, but it was terrible when playing the Middle Ages conquest.
