1. Make sure your Mac and Chromecast are connected to the same network, same router, and same router channel.

 

2. Launch the app on your Mac, and it would automatically scan your network trying to find the Chromecast which you can stream audios to. All available devices would appear in the “CAST TO” list once this process is finished.

5. To send your system audio to the Chromecast, please select "Live Audio" in app’s control menu. The first time you use this feature, it's required to download and install our "AudioCast" audio driver to capture the system audio. You can download it from our website by clicking the "Learn More" button in the popup message or clicking here. After the installation, please restart all apps on the Mac that  are playing audio and video, such as QuickTime, VLC, iTunes, Safari, and Chrome.

After the installation, please select "AudioCast" as the audio input source in the app's Preferences, select "Live Audio" again in the control menu, and the system audio would be sent to select device. Optionally, if you have other audio drivers like "Soundflower" that can capture the system audio, you can select it as the audio input source. However, it is not recommended, because third party audio drivers aren't fully optimized for this app. And there might be problems if you use them as audio input source.
