Demo: No sound

[sybesis]

Doesn't anybody use Pulseaudio with this Game?

Your config is Ok...I use pulseaudio too.
What is your graphic card?

You may have to use the libopenal.so that comes with ubuntu. I had a problem with libopenal that made penumbra completely crash but when using the libopenal that came with fedora there wasn't any problem anymore.

If you know how make symlink! rename the openal.so that comes with the demo to something else then do a link with the lib of ubuntu to the name of the openal.so file that came with the demo before renaming it.

/usr/lib/libopenal.so # mine is there
