Chromecast and Chromecast Audio are two different devices. The Chromecast is meant for video and audio streaming and aims to give users a ‘smart’ TV for the very cheap price of $30. The Chromecast Audio is meant to stream audio to speakers and give you ‘smart’ speakers without breaking the bank. Even though both devices are cheap, you might not want to buy them both and perhaps would like some way to use the Chromecast as just an audio streaming device. This is possible provided you aren’t trying to hook the Chromecast up to a pair of speakers. What you can do, with the right third-party apps, is stream audio from your PC or Mac to the Chromecast. Here’s how.
The app you need is called Chromecast Audio Stream. It’s very simple to use. Just download it, and run the app EXE. Make sure your Chromecast is set up and properly running. The app adds a Chromecast icon to the System Tray. Right-click it and select your Chromecast. That’s all it takes. Any and all audio that is played on your system will stream via your TV/Monitor’s speakers.
To control the volume, use the volume controls on the app that’s playing audio e.g. VLC player or YouTube’s media player. You will not be able to control the volume from your system’s default volume controls.
You need two apps to stream audio from your Mac to the Chromecast. The first is SoundFlower. Install this app on your Mac and then install Soundcast. Soundcast adds a Chromecast icon to the menu bar. Make sure the Chromecast is up and running and click the icon. From ‘Cast to’ option select your Chromecast and the audio from your Mac will start streaming to the TV/Monitor you’re Chromecast is connected to.
Streaming is nice and smooth with both Soundcast and Chromecast Audio Stream. There’s no lag to speak off but we won’t recommend overloading your network when you’re streaming audio. Both apps will stream any and all audio from your desktops so be very careful about what you’re playing when you’re streaming audio to the Chromecast.
