AudioNode.channelCount = 0 throws NotSupportedError

[rtoy]

The spec (https://webaudio.github.io/web-audio-api/#widl-AudioNode-channelCount) says NotSupportedError is thrown. The spec doesn't say, but presumably setting channelCount to be greater than the implementation's maximum number of channels should also throw.

In this case, IndexSizeError seems more appropriate.

It is not like "we can't do it", it is more like "you shouldn't do it."

Well, admittedly, when setting it to something greater than the max for one particular implementation, NotSupportedError makes sense, because it possible another implementation supports more channels.

[rtoy]

Leaving it as NotSupportedError is acceptable to me.

Resolution: leave as NotSupportedError for zero case, setting channelCount to be greater than the implementation's maximum number of channels should also throw NotSupportedError.
