Yo! Another heads-up on a new feature of PA which might be useful for some embedded use cases, beyond the desktop which I wrote it for. There's now a new module called "module-intended-roles". It looks for the PA_PROP_DEVICE_INTENDED_ROLES property on devices and moves streams which have a role that is listed in the space seperated value of this property to the device. This happens when a stream is created, as well as for existing streams on hotplug of devices and on hot-unplug of devices. What is this good for? For now only two modules set the property on their sinks: the bluetooth module sets it to "phone" when in HSP/HFP mode and the RAOP module sets it to "music". The effect is then that phone streams are automatically moved to a headset when it becomes available, resp. that music is automatically moved to a RAOP sink when it becomes available. Beyond the static definitions in those two mentioned modules you also can set the property when loading the alsa modules via "sink_properties=device.intended_roles=foo" or suchlike. This can be used for simple policy decisions. User-decisions and decisions made by module-stream-restore take precedence over the decisions of this module. i.e. if a user actively moves a phone stream away from the headset, then PA will obey and remember that. As a side note: module-stream-restore now too is active not only when new streams are created but also when devices are plugged or unplugged.
