Disable Google Home casting sound

I updated the script originally shared to include friendly fields when using the script in your automations.

  1. Copy the script below.
  2. Create a new script in HA.
  3. Go to the … menu and select Edit in YAML.
  4. Select everything and Paste the script you copied from below.
  5. Use the “Cast Media…” script as an action in your automations.
