I recently had my PC connected to my LG TV through the only HDMI output on my PC. For some reason, Windows created three copies of the TV in the sound widget. Only one of these actually worked at any one time (although annoyingly, which one worked would change after e.g. using a headset or putting the PC to sleep). As of now, only one of these appears as disconnected.
Being as I now have a different, sound capable monitor attached to this HDMI port, there is no reason for the other devices to be present. I would have thought that there should only ever be one output listed (the HDMI port) with the name changing to reflect the currently connected device.
I know that I can disable these devices manually, but as Windows seems to like adding extra redundant devices, and I have no plans to reconnect to the TV any time soon, is there a way to remove these device listings pernamently?
They do not appear in device manager (even when un-hiding hidden devices) so cannot be removed in this way, and the "uninstall driver" button (and all related buttons) are greyed out in the Properties window.
