Unfortunately, any program that uses quicktime audio out settings maps the channel outputs based on the quicktime channel settings. 4.0 still makes it 4.0 surround. The channels MUST say discrete or else it will not play out all 4 channels of audio or it will mix them down together (BAD). Still at a standstill here…
Maybe an applescript will do the trick? anyone familiar with how to set the channels to discrete using applescript?
