By Fredrik Andersson, 4 June, 2017 Forum iOS and iPadOS Hello! I want to send Youtube clips from my Iphone to chromecast audio, how to do this? Options Log in or register to post comments Comments chromecast If there is one in range, a button should appear near the top of the youtube app that is labeled TV. When you double tap it should send your audio and video to chromecast, or it might pop up and ask you what device you wish to connect to the first time. After that, I think it just pairs by default.
