Why is there no sound?

This articles explains what to do if you're not hearing any sounds from Cozmo.


When you're interacting with Cozmo, there are two place from which you can expect to hear sounds:

  1. Your device
  2. Cozmo himself

Note: applies only if Cozmo is not muted in Settings > Volume & General.

Your device

If you're not hearing music or game cues (things like narration during intro videos, prompts to play games, Cozmo detecting a cube, and the notes played by Cubes during Memory Match), check the Volume settings on your device (Volume Up/Down buttons) AND the Music level in Settings > Volume & General:


You also should take a look at the device itself to see if it has an issue and ensure the app is installed on internal memory.
