Comment (by lennart):

 Are you streaming *only* the center channel? Then yes, we do upstreaming,
 because you have 4 output channels and only one input channel.

 Run pulseaudio with "-vvvv" in a terminal, it will then show you the
 mixing matrix for each stream you create when you create it. It should
 show you whether PA does the upmixing for you. (You might need to stop the
 running PA first by issuing "pulseaudio -k" first.
