Upmixing of 2 channel audio appears to have been broken in the last couple
auto builds.

I have no special config files, this is all from a standard installation.
These setting produced upmixed audio up until the last couple builds for
the channel I played in the attached log. Attached to my receiver with an
optical connection.
