mike, I’m not sure what you’re doing but it’s definitely not correct.
I’d recommend that you create a new multi track sequence in Premiere and make sure that your tracks are setup as standard tracks. Copy your previous sequence into the new sequence and then try to send it to Audition.
A correctly set up multi track sequence in Premiere will open up in Audition as a multi track audio sequence with each track discreet mono or stereo and that includes submixes.
