From the Settings App

Method 4: Check HDMI Connection

A faulty or loose HDMI cable might be the reason you are experiencing issues of no sound from the TV while screen mirroring.

If your HDMI cable is not damaged, try adjusting them from both connection ends. If this does not work, you may need to replace the cable.

A firewall protects private data on the network you are connected to, and activating a firewall on your device can affect your sound output when streaming movies online.

If you have not set your iPhone to automatic update, do this;

  1. Open Settings>General>Software Updates
  2. Activate Download iOS Updates and Install Updates
