How to interpret the speaker test
This page plays generated audio so you can listen for sound output, stereo direction, treble clarity, bass response and unwanted noise.
What this test checks
- Whether the browser can create and play audio through the selected output device.
- Left and right channel routing for headphones, speakers and USB audio devices.
- Treble clarity, bass sweep response and rattling or buzzing during the full test.
- Basic tab audio behaviour, mute state and safe volume before deeper driver checks.
How to understand your results
- A good result is clean, balanced sound from the expected side with no crackling, buzzing or sudden dropouts.
- If both channel buttons sound centred, mono audio, accessibility settings or a single speaker setup may be collapsing stereo.
- Weak bass is common on small laptop speakers. Distortion at moderate volume is more concerning than limited low-end response.
- If this page plays audio but another app does not, the hardware is likely working and the issue is app-specific.
Common problems and fixes
No sound
Check system volume, tab mute, output device selection and Bluetooth headphone connection state.
Wrong side plays
Check headphone orientation, cable seating and any balance settings in the operating system.
Crackling or buzzing
Lower the volume, unplug external devices, try another browser and inspect speakers for debris or damage.
Bluetooth delay
Wireless audio can add latency. Retest with wired headphones if timing matters for gaming or editing.
FAQ
Can browser audio damage speakers?
The test uses modest generated tones, but you should still start at a safe volume and increase carefully.
Why does speech not always play?
Speech synthesis is optional and browser-dependent. The tone checks still run without it.
Can this test surround sound?
No. It focuses on browser stereo output, which is the most common issue for laptops, headphones and meetings.
