Currently, if remixing is disabled in daemon.conf (enable-remixing=no), playing
a mono stream to a stereo sink results in silence. There should be a
possibility to enable remixing only when adapting audio between mono and
non-mono.

The suggested solution is to add "mono-only" as a possible value for the
enable-remixing option (currently only "yes" and "no" are supported).

I already made a patch that changes the behavior of the "no" option so that
remixing between mono and non-mono would still be enabled, but that approach
got opposition: "no" should mean "no", not "no, except sometimes yes".

My patch is probably a useful starting point anyway, so here's a link to it:
