--- Comment #34 from Luis Alvarado luisalvaradox@gmail.com 2011-09-11 21:42:45 CDT --- This is fixed after 1.3.28 with the new Automagic audio driver selection and other sound changes made in this version. The introduction sounds perfect and when playing you can even hear more sounds from the environment, zombies and gun shots. The game feels much better now.
