- category
- AudioRenderCategory
A value from the MediaCategory enumeration indicating the categories of audio streams that will be monitored. The system may use the category of an audio stream to determine if it should be muted or have its volume lowered in response to a particular system event.
- deviceId
-
String
Platform::String
winrt::hstring
A string containing the unique identifier of a audio device for which associated audio streams will be monitored.
Returns
An AudioStateMonitor object.
Remarks
The method you use to instantiate AudioStateMonitor determines which audio streams are monitored. Other factory methods of the AudioStateMonitor class allow you to monitor the level of audio streams based on their AudioDeviceRole and whether the stream is capturing or rendering audio.
Call FindAllAsync, passing in the value returned by GetAudioRenderSelector, to get the list of DeviceInformation objects representing the available audio render devices.
