Replying on myself: I get sound when I in psclient.cfg

; Linux - OSS sound system
;SndSys.Driver = crystalspace.sndsys.software.driver.oss

take away the ; before ;SndSys.Driver = crystalspace.sndsys.software.driver.oss

Weather in this case I get a segfault sooner or later like:

xxx@xxxx[~/ps/planeshift]$ ./psclient
DEBUG: Software Renderer Initializing..
NOTIFY: Configured for driver [cristalspace.sndsys.software.driver.oss]

planeshift.application.client:

Must say that my system is configered for alsa basicly but when I change OSS in that line to alsa there is no sound either.

The Istaller worked good for me too but with some issues with sblive,

Linux Debian 2.6.12 Enlightenment P4 CPU 2600 Ghz Nvidia 5200

When using sb 128 pci I didn't have problems at all also not after upgrading.
But when I replaced the soundcard with SBLIVE 5.1 (full duplex) It sometimes segfaulted
and after upgrading Planeshift I had no sound at all, but no more segfaults.

Ok I couldn\'t make it work manually, then I tryed the script:
buildplaneshift.sh  wich you can download on  http://icarus.uic.edu/~ssenne1/
It worked well for me (Good work! thanks!)

Short explanation:
Make a folder in your home directory called planeshift (or alike) then download the script in it, open a console cd in this folder you made and type:
chmod +x buildplaneshift.sh
enter and then type:  
./buildplaneshift.sh
after enter it will automatically build it for you, be patient it takes some time.
Hope this works for others too.
