OpenAL sound error when trying to start Penumbra

[cortez]

Try and remove the openal lib from the lib folder in the installation directory. This should make the game use the system installed openal instead which might work better.

Thanks for your suggestion
before removing openal lib from the lib folder i get this message:

-------------------------------------//-------------------------------------
open /dev/[sound/]dsp: No such file or directory
Segmentation fault (core dumped)
Penumbra exited unexpectedly, please check
/home/cortez/.frictionalgames/Penumbra Overture/Episode1/hpl.log
for any error messages
Also try running
ulimit -c unlimited
And re-running Penumbra and try and recreate the error
then submit the generated core file or stack trace
-------------------------------------//-------------------------------------

removing libopenal.so.0
