I have no sound running the 64 bit version (1.3.13). My sound system is pulseaudio. Used the tar.gz version and /usr/lib/alsa-lib/libasound_module_pcm_pulse.so exists.
Check to make sure that you didn’t mute your audio before starting the game.
1.3.14. is now available for Linux, please try updating!
correction: 1.3.14 is not yet available for Linux. sorry for the confusion.
What linux distro are you running?
Gentoo Linux. Other games (being it open source ones or ftom the Steam catalogue) work just fine. Also other sound is working, so no muting. Also the game doesn’t shop up in pulseaudios mixer.
Ops sorry about that!
