gst_ks_device_provider_probe() is a no-braier, just runs ks_enumerate_devices() and reports the results. Monitoring is a bit more tricky. We have to create a dummy message-processing window and register device change notifications for it. As kernel streaming can (and should) be used for audio capture and audio playback, this change also has certain placeholders for such. https://bugzilla.gnome.org/show_bug.cgi?id=747757
