Comment(by lennart):

 Sure we can ask how many channels a device has. However the problem is we
 wouldn't now how those channels are mapped.

 I.e. which channel is L? Which R? What is Front? What Rear? Is there LFE?
 Is ther a Center? and so on. We cannot map which channel belongs to which
 position. That's why we cannot autoconfigure this for multichannel audio.

 For stereo this is easy since 0 is almost certainly left, and 1 is almost
 certainly right. But for anything beyond that we have no clue.
