I think there is a bug in FCPS2.
When you change a six-channel-sequence in the sequence-audio-settings from multichannel to two-channel-stereo for example and after that try to change again back to six channels.
The audio-routing-settings remain to the two-channel setting.
You have to manually set the routing for each track beginning with channel 3 (eg track3 -> order 3).
This is very unusefull. Also there is no summarywindow showing all the routing-settings.

hope it helps.

cheers
