Under the linux version of LOG, front and rear sounds are reversed. That is, under my 5.1 setup, sounds originating from behind come from the front center speaker (and vise versa). I do not observe this problem while running LOG through WINE. I believe my channels are mapped correctly based on the results of:
speaker-test -c6 -l1 -twav
I'm running Archlinux x86_64 and Pulseaudio 4.0. I see this problem when running the game through the standalone installer, and when running through Steam.
Is anybody else running LOG on linux with a 5.1 surround system?
