I don't know if this is the right place to post this, but here it is:
I found that using the packman repository for gnaural2 didn't work with sound, but I found that doing the following got it to work:
1. make sure that alsa-oss is installed
2. change the open command in the application launcher to aoss gnaural2
This seems like a pretty easy fix to get gnaural2 to work out of the box if it could be changed in the repository
The place where I found out how to do this is here: http://ubuntuforums.org/showthread.php?t=863967
Thank you
