Screen mirroring through Chromecast or Samsung smart TV problems

Has anyone had any success screen mirroring to either Chromecast or a Samsung smart TV? If so, are you rooted or stock? If rooted, what ROM?

When I try screen mirroring through my Samsung smart TV the video comes through, but the sound does not. When I try through Chromecast, it disconnects immediately when I try to connect.
