Description
I want to stream the audio from youtube to my chromecast audio but it doesnt work. My speaker system shows up as expected but otherwise nothing happens. I have tried both the media control on youtube and to cast the the site by right clicking and clicking cast. I see more options as soon as i cast from spotify instead such as the song name and more.
