On Windows, you need Chromecast Audio Stream. Once it's installed, just select your Chromecast from the tray icon and your audio will start streaming. On Mac, you can use Soundcast. Here, you'll first need to install Soundflower, then install Soundcast (you might need to reboot after installing Soundflower).
