KS glitch on Ubuntu 11.04

[fohfuu]

I tried to boot KS today from the .sh file as normal, and whether I run it normally or in terminal the game just flashes up for less than a second. traceback.txt appeared in my folder:
I'm sorry, but an exception occured while executing your Ren'Py
script.

IOError: [Errno 19] No such device

Any help would be greatly appreciated

[Nekken]

That looks like an audio error. Are any other programs giving you trouble with sound?

[fohfuu]

Nope, no problems with audio.

I'm having a similar issue on 11.10. Maybe something to do with unity's ui?
