I don't think this is currently possible. You'd need module-combine-sink
for combining the front and the rear speakers, but module-combine-sink
doesn't support selecting some channels for one output and some other
channels for another output.

Even if module-combine-sink supported such splitting (it shouldn't be
hard to implement, if you feel like contributing patches), there would
still probably be issues with timing. I'd imagine that good surround
experience would require very good synchronization, and I don't think
module-combine-sink provides that. (It does provide some
synchronization, but from what I've heard, it's far from perfect.)

Some details about what you've tried and what errors you're getting
would be useful (if you still want to run pulseaudio in the system mode,
given what I said above).
