Are you using Linux? If so, what distro/version?
I've been getting this:
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/i386-linux-gnu/alsa-lib/libasound_module_pcm_pulse.so
Adding that line got rid of the message but still no sound. The game works fine, but clicking on music or sound in options would CTD with:
Traceback (most recent call last):
