I just downloaded the demo, and I sadly have the same audio issues which have been reported here over the course of the last few months (game freezes, renaming Audio helps). I have no custom MP3 codecs installed at all. None of the other solutions (converting all files to WAV or MP3 and fiddling with DirectShow filter settings) helped.
Audio Hardware: Creative Audigy 4 + Realtek onboard
OS: Win 7 SP1
