I have a microphone which does not have an off switch. It is USB and, if connected, it is powered on. Normally, I don't want the microphone on so I have to go into "Sounds", right-click the device, and select "Enable/Disable" or select "Properties" then "Use this device/Don't use this device".
It would be more convenient to have an icon or something I could just click once to enable/disable. I've tried some of the suggestions with devcon but it enables/disabled the driver itself and doesn't really work well. Also tried nircmd but couldn't find anything that really met my need.
