No audio Ubuntu 10.10 64-bit

Game: 

Hey guys, does anyone have a clue on how to get audio to play nice in this game. I'm having no issues except for the lack of sound in this game. I've researched and looked around and have found no workarounds for this particular issue.

Forums: 

I think there are two ways/solutions:

1st: use oss as sound system

2nd: install oss-compat

Thanks sixsixfive, I found an even easier workaround:

padsp (path to postal2mp launcher) in terminal

Works like a charm! Thanks for the help.
