That "Realistic Sound Travel Time" on my systems also results in troubles. SH4 is very "sensitive" when it comes to 'sound', in that Windows wants to 'virtualize' the audio, whereas the game wants a set address to find things and wants to manage it all itself. Also, Windows does NOT like it when the audio stream changes bit-depth or format (DRM), and SH4 wants to manage, and is full of mono & stereo, 8k - 44k audio in wav, mp3, and ogg formats, all depending upon the "source" of the audio call. All that said, a headphone that is attempting to take basically a "stereo" feed from the game and convert it, might very well be confusing the issue. Is there a way to turn that off temporarily Delfi, and just have "normal" left/right from the cans, for a test? Some of your 'important' game audio might be being confused as 'background' audio for the rear channels.
