+Update audio device configuration
+
+Rework the audio output device configuration to match the expectations
+of the PipeWire output sink configuration in the gstreamer output code.
+Currently, this means that the role is being stored as the device name
+so the gstreamer code can use it when setting up the output sink
+properties.
