Gets the suggested audio stream whose volume should be changed by the hardware volume controls.

Set method documentation [Android Documentation]

Suggests an audio stream whose volume should be changed by the hardware volume controls. The suggested audio stream will be tied to the window of this Activity. Volume requests which are received while the Activity is in the foreground will affect this stream. It is not guaranteed that the hardware volume controls will always change this stream's volume (for example, if a call is in progress, its stream's volume may be changed instead). To reset back to the default, use Android.Media.AudioManager.UseDefaultStreamType.
