I was trying to assist a group about their attempt to take a multitrack session in Adobe Audition into a 5.1 mix. The stereo tracks were split into left and right channels to so we could have six mono tracks (L-R-LFE-C-BL-BR). Using the pan control on the properties box we had tracks 1 & 5 hard panned left and tracks 2 & 6 were hard panned right so that a stereo approximation could be reached lacking only the 3-dimentional aspect.
What happened when we used the multichannel encoder preview was that tracks 2 & 6 that were hard-panned in the right channel disappeared. The first attempt to workaround the problem was was to assign separate busses and hard pan in the mixer window. That failed so we took out the busses and used the envelopes. It still didn't work, the two right channels showed up blank in the 6-way VU meter. If I removed the pans (wrecking the easy transition from stereo to mulichannel) everything came out mono
I left frustrated with the advice to check for an Audition update in the event this was a bug. It almost seems this encoder was only made to make simple conversions, yet I am still baffled that most of the layout did indicate that I was correct in thinking 6 mono tracks would be treated as each separate channel in the encoder.
This problem is a bit hard to explain in forum-style but I figured I'd ask anyway.
