This method of casting only works on Android devices running Android 5.0 or higher. To cast Pinguin Radio to your chrome cast, you need the Google Home app. This can be downloaded in the Google Play Store.
First, make sure you’re connected to the same network as the chrome cast. Then start the Google Home app. Click on the chrome cast you want to use to cast Pinguin Radio. Next, click on ‘Cast my screen’ -> ‘Cast screen’. Finally, go to Pinguin Radio and chose your favorite Pinguin stream!
Does the stream drop out after a certain time? This may be due to the battery saving settings. In this article, you can read how you can solve this.
