The Raspberry Pi supports audio output over either HDMI (default) or 3.5mm audio jack (headphone jack).
To change the output mode, follow the steps below:
- Navigate to your screen.
- Click the "Settings" button on the top right.
- Set "Audio Output" to "3.5mm jack".
- Click the "Save" button.
Please note that audio setting changes may take approximately 15 minutes to go into effect.
