I have just updated the Linux version to 1.3.2 like the Windows and Mac versions.

Good news, it appears the GameMaker upgrade I did since last version fixed both the Xbox gamepad compatibility issues and the YYC (better compiler) issue too!

I could not fully check the positional audio because for some reason, audio only comes on the right on my Ubuntu install (I suspect this is a driver issue) Let me know if it doesn't work as expected.
