The problem may bee that you mixed up two different things: Plugging and Unpluggging vs. creating and removing subdevices. My own driver doesn't care about unplugging, it also doesn't have a Topology. But it dynamically creates subdevices. Restarting the app is needed in any case I think. /Uwe Am 26.11.2010 08:03, schrieb Robert Bielik: > Dang XiaoHui skrev 2010-11-26 07:50: >> scenario 2： >> We manually set Device B as Default device, we can hear the music in Device >> B.
