Whenever something changes on a stream, module-device-manager (with do_routing=true) will re-evaluate the stream's routing to react to stream role changes. module-device-manager will not reroute streams that have pa_sink_input.save_sink set, which avoids rerouting of manually routed streams most of the time. When an application creates a new playback stream, it may set the sink for the new stream. That counts as manual routing, so device-manager should not reroute the stream as long as the requested sink stays available, but such streams don't have save_sink set, so rerouting does happen. An example: paplay --device=foo somefile.ogg That will play the audio to sink "foo", which in this example is not what device-manager would prefer to use. Now let's change the volume: pactl set-sink-input-volume 42 +5% That volume change will trigger rerouting in device-manager, so the stream gets moved to a different sink! We should make it possible to distinguish between all three cases: * manually routed streams with persistent device configuration (can be done currently by checking save_sink == true) * manually routed streams with ephemeral device configuration (can't be done currently, except during stream creation) * automatically routed streams (can be done currently by checking save_sink == false)
