This seems to have killed off the possibility of sane audio output with Firefox + PulseAudio + surround speakers, until the next release of PulseAudio.

Basically PulseAudio currently either does "remix all the things" or "remix none of the things". With surround speakers this is terrible, since you get to choose between either "upmix mono, stereo or surround to every speaker", or "output stereo/surround normally but throw away mono entirely": https://bugs.freedesktop.org/show_bug.cgi?id=94563 and https://bugs.freedesktop.org/show_bug.cgi?id=62588

A while ago Firefox gained a workaround for this: https://bugzilla.mozilla.org/show_bug.cgi?id=1257050 but that's no longer working as of Firefox 54, presumably because of the changes for this bug?

Any way Firefox can resume internally handling mono -> stereo upmixing until PulseAudio 11 is out (in which there is finally a "just behave sanely" option ;)) ?
