Plan a Silent or One-Sided Audio Check

Compare the selected audio route, channel position and another output with low-volume playback and a printable evidence record.

Your working record stays in this page. No automatic device access, media capture or saved test history. Copy or print only if you choose.

A silent browser tone does not identify a failed speaker. The browser produces a signal, while operating-system routing, application volume, mute controls, adapters and physical outputs determine what is heard. This plan uses your listening observation without claiming to measure hearing or calibrate equipment. Compare a short, comfortable sample rather than increasing volume until something becomes audible.

Before the comparison

Comparison 1 of 3

Check the intended route

Confirm the operating-system output and application volume, then deliberately play a short centered tone in Audio Output Test. Browser output selection is available only where supported.

Why it matters. A browser without output selection normally uses the system route. A selected device may still be muted or unavailable, so the observed sound matters more than the presence of a device name.

No tone is heardThe silent path remains unresolved.Check mute and volume controls, then compare another application or a known-working output at low volume.

Comparison 2 of 3

Compare channel positions

Play left and right separately using Left Right Speaker Test. If they sound centered or reversed, note mono or spatial processing settings before changing one setting.

Why it matters. The page routes browser audio channels but cannot listen to the physical output. Channel mixing, an adapter or application processing may change where the sound appears.

One side is missingThe asymmetry is worth comparing, not yet a speaker-driver diagnosis.Replay the same sample with another suitable output or connection.

Comparison 3 of 3

Compare another output or application

Keep the sample and volume consistent while comparing a suitable second output, or use the same output in another application. Record which single factor changed.

Why it matters. A problem that follows one output is different from silence confined to one application. A physical output still needs manufacturer checks before you name a damaged driver, amplifier or cable.

Your private comparison record

Use a general device description, not a serial number or private recording. Do not enter passwords, complete typed messages or sensitive personal information. Leaving or reloading this page can discard the record; the site does not save it.

How to describe evidence

Illustrative example, not a measured case report. A centered tone is audible on headphones but not on built-in speakers at the same selected app volume.

Useful conclusion. One playback path worked and the speaker route remains unresolved. This does not establish which physical speaker component failed.

Stop conditions and limits

This is not a hearing test. Avoid prolonged or high-volume tones. Disconnect equipment that is damaged, sparking or unusually hot and seek qualified help.

This workflow cannot certify hardware, decide warranty eligibility or replace model-specific inspection. It does not request camera, microphone or controller access. Dedicated tests require separate deliberate actions.

Primary and official references

These sources document browser behavior or platform troubleshooting. Our comparison sequence is an editorial workflow, not a manufacturer-approved repair procedure.

Questions about this comparison

Can the page automatically tell which speaker works?

No. Playback is generated by the browser and confirmed by your listening observation. The planner does not use a microphone to grade the output.

Why compare another output?

It separates an application that cannot play from a particular route that remains silent. Record the exact route because outputs do not share every component.
