Sound on Debian Jessie Linux

I have spent all day at work trying to get the sound to work in my game on our Debian Jessie Linux system. The game plays just fine, but there is no sound. We have the PulseAudio soundcard. Most of the articles I’ve read have said to change a file and uncomment something, but the problem is that I do not have administrative access to even open these files, much less change them. So my question is, am I just out of luck here, or is there some work around? I read that closing everything that might use the soundcard would work, but I coulndn’t get it to. I’m using the newest Java update and just playing audio with audio.play() in AWT. Also should state that the sound plays just fine in Windows. Thank you guys!

Edit: I am not getting any errors about sound in the console either.
