For me, Reece, the hardest part is understanding the audio stack in Linux, which might be why you have issues with getting WaveLab to run correctly. Which version do you have, and what audio device is installed? Some of your other apps might have audio issues also... does Far Cry use 3D audio?
My Ubuntu 16.x didnt' have any issue at all with getting the onboard audio to work, I definitely have issues with recording and mixing multi-channel, and I cannot for the life of me, figure out how to get my EMU 1820M to work in it, though there are multiple examples of doing so on several sites...
Like modding SH4, I'm "thick" on some aspects of things...
- it just won't sink in...
