[SOLVED] Chromecast 'stealing' broadcast from other devices

[al92]

In a school I work in, there are 3 chromecasts connected to display screens - an entrance, a meeting room and a staff room.
I'm repeatedly finding that if you cast from google Chrome (whether it's desktop, tap or browser mode) to either the entrance or staff room screen, after a short while, without any human interference, Chrome starts casting to the meeting room instead. Sometimes this happens after, say, 30 minutes, other times 10 minutes or as little as about 45 seconds.

Does anyone know a) why this is happening and b) how it can be fixed? I'm not experienced with Chromecasts; I set the staff room one up using the Home app but didn't set the others up myself.

Use the following link (or other similar links) to double check the configuration settings.

If all seems well then delve deeper:

Windows 10?

Take a look in Task Manager (Startup tab) and Task Scheduler.

Some app may be running or being launched that starts casting to the meeting room.

I would suggest complete resetting all 3 Chromecasts and then using the Google Home app to set them all up together. They can be a little bit of a pain.
