Loic did point out that nothing hardware decodes 5.1.

Did I say anything else ?
You must understand that hardware manufacters will target a level and
adjust any hardware requirements to it as closely as possible, in order
to reduce the cost. A hardware decoder supporting SD at most, but 16
refs on SD, ought not exist ( I'm not affirmative, because there are
crazy people out there... )
