Strange 5.1 Master Fader Behavior When Bnc to Disk

[kcupper]

This is a strange one:

When attempting a bounce to disk, or for that matter a bounce within the session itself, the 5.1 outputs go into this strange mode where all the outputs are jumbled, kinda of like hearing just reverb returns.

For example, if the 5.1 outputs are configured
1 = Lf
2 = C
3 = Rf
4 = Ls
5 = Rs
6 = LFE

when trying to bounce to disk or to a 5.1 audio channel, the output is

1 = nothing
2 = nothing
3 = garbage
4 = reverb return
5 = reverb return
6 = nothing

The problem ONLY occurs when there is a quick fade-in on the master fader immediately AFTER the bounce start point. Removing all level automation from the master fader eliminates the problem.

I can't tell you the things I started to troubleshoot before discovering this issue purely by accident. This problem doesn't occur with a regular stereo session.

Just wondering if anyone has come across this or is able to duplicate this behavior. Thanks.
