We discussed the question of channel handling in the recent past, as part of our handling of ISSUE-9 

http://www.w3.org/2011/audio/track/issues/9

My understanding of the consensus so far was that:

* The API should support and (by default) match the channel configuration specified by the hardware
* The spec should not constrain the channel support to "typical" contemporary layouts 


I guess this leaves us with two questions:

- Should we normatively specify the channel ordering/naming for typical layouts
- How can we ensure interoperability between implementation in their naming/ordering of channels in atypical layouts (say, a 100-speaker concert configuration)
