- Lower your system volume, then start the speaker test.
- Play short tones through the left, right, or both channels.
- Confirm what you heard to create a local channel summary.
What this result cannot prove
- Many browsers use the system-default output and cannot select a different speaker.
- The test confirms audible routing; it does not score speaker fidelity.
