[ubuntu-za] Audio playback problem

[Jan Schoeman]

Hey... looking for some advice. ^.^

I'm running an Acer Aspire 5735 (slightly irrelevant but I thought I'd
mention) with Karmic Koala.  All my audio works fine but I am having some
issues playing audio from a java application (which works on another system
- if you are interested in code its here: http://pastebin.com/dhFKyxrg).
When I run it gives me a exception...

*Audio Device Unavailable*

...which made me think that my audio device was being "held" by some other
program.
( I did some research and found
http://linux.dsplabs.com.au/lsof-grep-snd-how-to-free-a-linux-sound-device-p25/)

I ran the command:

lsof |grep snd


which gave me

pulseaudi 2190        jan  mem       REG        8,6   420372    4254042

now it seemed to me pulseaudio was handling my sound, and i'm pretty sure it
should, so I reached a dead end here.

Any clue how to get the java program (which I am running from eclipse) to
play audio succesfully?

Let me know if you have any ideas on this.

Thanks
