Some platforms use hardware > mixers that have a limited amount of channels. Actually, I am interested in the number of physical speakers - or more specifically the number of channels actually output from the device. I have a multichannel stream and a professionally downmixed stereo stream and if there are only two output channels I'd rather provide the stereo stream than have the device do its own downmixing. I distinguish between the number of physical speakers and the number of output channels because there are setups where the audio output is making proper use of the 6 output channels but has less than 6 speakers (for example soundbars, where there is audio processing which tries to simulate the effect of surround speakers using phase manipulations etc.). I consider those setups as having 6 output channels. But if the device is doing straight downmixing to stereo, I'd rather provide the professional stereo stream (which is also less bandwidth). …Mark >
