OpenAL Audio Update: Use 1.0.2553 Patch instead!

[onegreenparker]

Running Ubuntu 7.04,
HP6715s Laptop,
Downloaded PenumbraOvertureDemo-1.0.1.sh,
Ran the .sh in terminal, installed OK.
Started game OK.
Sound clicks every so often, and sounds a bit scratchy at times.
(And video extremely low, but one problem at a time)
Downloaded PenumbraOvertureOpenAlUpdate.sh,
Ran the .sh in terminal, installed OK.
Started game, no start, on next start I get a message ¨Game did not end properly last run, resetting configuration¨
Click on Close.
Restart PC, restart game, same error as above.
Attached is hpl.log
Any fix before I buy the game?

As a Linux user, I am starved for games so please help.
