I have a problem with Audio from the speakers activating VC commands so my solution for this is to put VC into standby whenever I change my default playback device to speakers.

The way it keeps track of default audio being changed is keeping watch on a file. If the filename is "1" that means speakers is the default audio, if the filename is "2" that means headphones is the default audio. but the watcher keeps missing the file change event. Is there a reason for this?
