We are finding that anytime a new audio device is added to the PC this device name is retained in the room configuration drop down field even though that device is no longer connected. Furthermore, if any audio device is named on the PC, it will create an additional entry for that device but add a number to it if that device is removed temporarily for service or other reasons, as well as keeping the original device name. This creates confusion and recording errors as any current scheduled recordings will default to the originally named entry and not the new device name unless modified in the config. This can become quite unwieldy. The only way to clear this cache of device names is to delete the room altogether and re-add it which affects any current schedules and access to past recordings when doing a search for past recordings in this room (they don't show up). A way to clear or modify this cache of anything other than what is connected would be helpful.
