Guides

macOS + Android

Set up CastSound on macOS and Android: install both apps, allow microphone and local-network access, and connect your devices over Wi-Fi or USB.

Follow these steps to set up CastSound on a Mac and an Android phone. The whole process takes a few minutes: one app on the phone, one app on the Mac, and one connection between them.

Choose CastSound in the app you are using

Choose CastSound as the Mac sound output to hear computer audio on the phone. For calls, choose CastSound as the microphone input. To appear on video, start the camera in the phone app and choose the CastSound camera in your meeting app.

If you get stuck

Check these three things

  • Both devices are on the same non-guest Wi-Fi network.
  • The phone allowed microphone and local-network access in Android settings.
  • The Mac allowed the CastSound audio components to load in Security settings.
