Currently it would seem that one has to choose between stereo or surround output, e.g. an hdmi 2.0 sink or an hdmi 5.1 sink.
This means that either multichannel content such as DVD-A, movies or other video content will be downmixed to stereo or that stereo content will be outputted as multichannel (with several 'silent' channels or upmixed, depending on the 'enable-remixing' setting). The behaviour prevents receivers from upmixing the signal to surround themselves with arguably better algorithms such as DPL2, Neo:6 or Logic-7.
Therefore, I would like to request a feature to have detection for the max number of channels in the active source(s) and use the appropriate sink in the right mode. This will allow audio to be passed through 'natively' and leave the processing up to the receiver.
