Speaker Test

Intended to perform testing on the device's built-in speaker.

Prerequisites

• Device with an internal speaker.
• Headphone Jack for earphones (optional).

How it looks

Make sure to set the sound level to an audible volume using the volume setting on the top bar panel. Repeat this test using earphones if a headphone jack is available. The focus is to verify the function of the headphone jack; ensure the sound is routed to the earphones and the internal speakers are disabled when the earphone jack is plugged in.

The source sound test uses a dual mono audio source: the left channel contains voice and the right channel contains music. This setup allows the tester to easily detect whether the left and right speakers are functioning and oriented correctly.
