> >Maybe audio drivers just fail at it or the two HDMI receivers I tested
were bad at their job, but at least on Windows trying to send different
layouts of the same channel count usually results in the same layout being
used for all variants, which is why I added a mode to pad it with empty
channels to one of the "standard" modes.

support the specific layout you tried (this seems to happen often with
obscure layouts).
I think I first noticed the problem on a 5.0 (ie. default 5.1 without
sub), which would somehow swallow the center channel when played like
this, I would think thats not too obscure, but shrug. Padding with empty
channel was easy and ensures compatibility. :)
