advanced 737 intercom system

[dc8flightdeck]

The goal is to provide seperate audio selection functions between the pilots.

Im starting to research the possibilities of using three real gables audio selectors in the 737 sim. It apears to me that there is no possibility to seperate the radio audio selections from FSX and pilot edge between the capt, FO, and observer.

I assume I would need multiple sounds cards that send seperate audio from FSX to the gables, but FSX cannot send audio from each COM and NAV radio seperately through individual sound cards, correct?

Ive any of you have tackled independant audio selection for the pilots  Id be interested in hearing your approach.
