That was the source of my misunderstanding. I was assuming a model where a single pin can transport multi-channel audio, and if you have N channels, they should be in the first N logical locations (whether interleaved or not). And I do prefer this model rather than having each pin be a mono stream.
Using hints to auto-connect unknown formats is clever, but I prefer enumerating all supported formats. Manufacturer specific formats can be published and identified by a manufacturer ID of some sort.
Hints could possibly be offered in addition to the enumerated formats to provide legacy plugs a way to connect to newly defined formats?
I have a concern about how the formats are enumerated. We need to be clear to differentiate the physical format from the logical one. For example, various 2-channel formats are listed below:
stereo Lt,Rt (from various encoders) M/S binaural loudspeaker binaural
But these should all be able to connect to say, a stereo limiter. Physically, these are all 2-channel PCM streams. The additional logical information is important in cases like distinguishing quad from L, R, C, S, or determining the channel organization in 5.1 or other surround formats.
