Hi, I was wondering if anyone could help me with my problem. I have a 2013 macbook pro and an airplay speaker. When I play music on my itunes the sound streams to my speaker without any problem. But as soon as I put on a movie (on itunes) the audio starts playing on my laptop and the airplay icon disappears. To clarify I am trying to watch movies on my laptop but only stream the audio through airplay into my airplay speaker. Is there any reason why it does not work? Hope someone could help me with this.
