OpenAL problem?

[elsenator]

I seem to have a sound problem of some sort. It complains about a missing dsp device node. But isn't that used only by OSS? I don't have that node.

This is the error message i get:

which: no chcon in (/usr/kde/3.5/bin:/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/4.1.1:/usr/i686-pc-linux-gnu/gcc-bin/4.1.1:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/usr/kde/3.5/bin:/usr/qt/3/bin:/usr/games/bin)
open /dev/[sound/]dsp: No such file or directory
./penumbra: line 9: 7838 Segmentation fault ./penumbra.bin "$@"
Penumbra exited unexpectedly, please check
/home/senator/.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

And this is the last part of the log file:

I've tried installing as root too, but that didn't make any difference.

Any ideas for a solution? Oh, and i have the full version 1.0.596
