Declaration

Swift

public func whenSelectorChanges(_ selector: AudioObjectSelector<AudioSubdevice>, inScope scope: PropertyScope = .global, onElement element: PropertyElement = .master, perform block: PropertyChangeNotificationBlock?) throws

Parameters

`selector`	The selector of the desired property
`scope`	The desired scope
`element`	The desired element
`block`	A closure to invoke when the property changes or `nil` to remove the previous value
