		* Spatialized channel layouts.
		* A spatialized channel layout is one where each virtual speaker position is rendered
		* at its corresponding virtual position, and is not downmixed with any other.
		* For instance if a spatializer is only capable of distinct positions for 5.1, it would only
		* return 5.1:
		* - the list wouldn't include 4.0, because that mask is "contained" within 5.1
		* - the list wouldn't include 7.1 (and so on) because the side and rear channels would be
		* downmixed together.
		* Another example is a spatializer that can only spatialize up to 9 channels (not counting .1)
		* and that supports 5.1.4, and 7.1.2, the list should include both.
		* The values must also be part of the values reported by supportedChannelLayout.
		* The array containing the values cannot be empty.
