First, did the opponents present a use case when a pure "no" (with all associated side effects) would yield the correct result for all use cases? Second (semi-trolling, don't take too seriously) remixing by channel copying and linear summation is so old-school! No modern 5.1 receiver does it by default when fed a stereo signal over SPDIF or HDMI. They have a US-patented upmixing algorithm from Dolby inside, using Z transformers and even non-linear elements, and most so-called "stereo" records are produced with that "matrix decoder" in mind. So, once this fancy upmixer is completely reverse-engineered, it should be an option at least in the countries where the patent is invalid. And yes, this does mean that the "enable-remixing" option is a misnomer, as it is not a boolean. -- Alexander E. Patrakov
