If you want to have the option to remix or not depending on random
(runtime) whims you can also load module-remap-sink and give a 2 channel
map setup to it and set the remix=no argument too.

That should allow you to move streams to that device that you do not
want upmixed. PA will remember this for you for next time.

Something like:

pactl load-module module-remap-sink sink_name="stereo" master="<NAME>"
master_channel_map="front-left,front-right"
channel_map="front-left,front-right" remix=no

I'm going from memory so the above is almost certainly wrong, but the
gist is right :p
