The new cast feature in recent builds of chromium is not working for me. It fails to find any devices. Looking at the debug output it says: "media router not defined. source:". After a bit of googling I found you can revert back to using the old cast extension by following these instructions: https://support.google.com/chromecast/answer/6349849?hl=en That being said the new cast feature is a lot nicer if we can get it to work. I am using it on my other computer and it's great being able to adjust volume (something the extension can't do). Cheers, Alex Matviychuk
