Hi,

Same problem here on 11.10, 64bit.
I get the same messages as Johannes.
The game is successfully playing audio even while printing the "unable to prepare stream" errors, but asserts when I shoot.

I am seeing this with Ubuntu's openjdk-6-jre Version:
6b23~pre11-0ubuntu1.11.10.1 and also with Debian's openjdk-6-jre
Version: 6b24-1.11.1-1 (also 64bit, unstable repo).

Bug description:
  When I run the game mojam from humblebundle.com I get the following
  error message. The error occours after several seconds after start.
  The game definitly works under windows, so I guess it is a bug between
  openjdk and pulseaudio.

  Note, this happens with openjdk 6 and openjdk7
  openjdk-6-jre 6b24-1.11.1-0ubuntu1
  openjdk-7-jre 7~b147-2.0-1ubuntu2
  Ubuntu 12.04

  java -jar mojam.jar
