Feedback given in
As Marcus pointed out in
maxNumberOfChannels doesn't seem to really work and an array of values would
make more sense.

We don't think that setting numberOfChannels to a configuration that isn't
supported should throw an exception, since that's likely to result in unhandled
exceptions when authors have only tested with one speaker configuration. For
example, it's to be expected that authors will set numberOfChannels to 2
without checking maxNumberOfChannels, which will fail on smartphones with a
single speaker. Instead, we think that the requested number of channels should
be used and mixing should be applied if the hardware doesn't support it.

Note also the typo in "If this value is 0, then this indicates that
<code>maxNumberOfChannels</code>" which should be numberOfChannels.
