Nokia Lumia 820 - I am not receiving audio when playing music or games on my Lumia phone

  1. Restart your phone by pressing and holding the power and volume down keys simultaneously until the phone vibrates. Release and the phone will restart.
  2. After this operation, you may need to re-adjust the volume. Use the volume keys to reach the most comfortable sound level (scale 0 to 30).
  3. If possible, try a wired headset.
