Discussion regarding my Edge Google Cast driver is taking place in this other topic for now.
It is a port of an existing DTH driver and requires another package to be running on a local computer, so it is probably of primary interest to the legacy driver users.
It is not as robust as the Roku driver, in that you can’t really have full control over a Chromecast device (launch Netflix, emulate keys, etc.). But it can pause/play/stop currently running media and show what is currently playing. Its usefulness is more of a speaker controller for compatible Google Cast speakers like the Google Assistant devices (Nest mini, etc.)
