According the Creative Labs NewsGroup it is possible to enable 3DSound and EAX by utilizing OpenAL. OpenAL is a joint effort to create an open, vendor-neutral, cross-platform API for interactive, primarily spatialized audio and supported by Creative Labs. Therefore it is likely that this will only work on Audigy/Live! (added: as OpenAL is not supported by other hardware vendors so far) cards... What you need to do: Open up the the config files (for SP or MP mode) in notepad (located e.g. C: Program Files LucasArts Star Wars JK II Jedi Outcast GameData) Adjust the following setting so that it is enabled: seta s_UseOpenAL "0" to seta s_UseOpenAL "1" This option is not available ingame so you have to do it manually. Some user report performance hits when enabled - I'm going to test it myself when reviewing the game over the weekend...
