The game is working fine with any sound device in the sound options.
Exception is OSS Software. When I'm choosing it - game sets PulseAudio device.
It don't want to start launcher when the sound device is "ALSA Software on default".
Another ALSA Software (analog, digital and hdmi) doesn't getting any sound, but they are not causing game not to launch.
If the cfg file is needed, I'll post it here later.
P.S. The game rocks. Do you have any ideas to distribute game in Russia like the Penumbra series? If that so, I'll definetely buy it
