Thanks for the feedback, one other point I'd like to settle is the naming.
 I've been thinking that a .numberOfChannels attribute isn't the right
name, but instead should be .baseNumberOfChannels, or
.numberOfChannelsHint, or something like that.  For now, I propose the
attributes be:

.channelCountMode
.channelInterpretation
.baseNumberOfChannels (which is ignored if channelCountMode=="max")
