Device or resource busy means that something else is using your sound
card. It can be eg. artsd used by KDE and ran by default.
UPDATE2 as the name says is a second update for the Linux client which fixes
that issue.
Remove everything except art and run the UPDATE2 which can be found at
http://planeshift.xpam.de.To these who likes to backup the Internet:
I see the old files are still available somewhere so If anyone mirrors files
available on any my site be that kind and email me with URL and your contact
email where I can send updates so you will not keep distribute outdated files
otherwise you are NOT helping. Generally you should also notify Talad (the
Planeshift project admin) about the fact of keeping Planeshift files on your
servers so be that kind and include a carbon copy to info at planeshift.it.
Regards.
