@Morphine:
Perhaps this might work…

Nice find, thanks for digging that out!
Yeah, as I suggested in my original post: If the various sounds are played on different channels (even while within a single audio device), one could try to feed these audio channels to separate amplifiers/speakers/headphones.
But that means a bit of tinkering and cable clutter most likely resulting in a connection variant only suitable for Falcon (if any).
For enjoying hi quality audio in any other application, one would have to restore the default connections between soundcard and amplifier/speakers.
So yes, if in-cockpit sounds and ambient sounds are channel-separated already, then this is a possible workaround for those that really want to separate them. Of course!
But not quite an equally comfortable substitute for this use-multiple-sounddevices-ingame idea. 😉
Btw. as Dee-Jay (in this linked thread) promised to kiss butt for a feature like that, I take it there seems to be quite some interest for it. Maybe a coder with a bit too much sparetime jumps in on THAT offer! 😄
