Constants describing a media role of a control. These constants are mapped to PulseAudio media role property and therefore are only available when using the PulseAudio sound system.
Media roles are commonly set by applications to indicate what kind of sound input/output they provide and may be the defining property of stored controls (for example an event role stored control can be used to provide a volume slider for event sounds).
See the PulseAudio documentation for more detailed information about media roles.
