I have the same issue with Xbox One controller. I've configured rumble in the settings, but my controller has never vibrated. I've extensively tested (by using "test" feature) different ranges between -500 and 500 and can never feel vibration.
5.0-4835, applies to countless older Dolphin revisions, but I haven't configured rumble before.
