1. So is Microphone listed in Recording Devices or not? I'm not referring to the Speakers.
2. If the Microphone is not listed in Recording Devices, when you right-click and check both 'Show Disabled Devices' and 'Show Disconnected Devices', does it show up?
3. If the Microphone is listed in Recording Devices, have you right-clicked on it and clicked Set as Default?
