We've just added a Linux build!

It should be easy to just pop in a Live distro USB stick and just boot from that for a test-run. Maybe you've got an older machine still around that you don't use anymore? But my guess is has as much to do with me not being able to build the project due to the missing Wwise parts, so it's quite possible sound is missing because of that...
I don't know what alternatives there would be and how difficult it would be to overhaul the whole sound system in your game, but it's something you might want to keep in mind for your next project...
