Quick answer
What Audio Output Test tells you
Check basic browser audio playback and show output-device selection only where setSinkId is supported.
- Observed here
- AudioContext availability, Short test tone, Output selection capability.
- How to interpret it
- A played tone checks the current audio route by your listening observation. Browser output selection appears only when supported; otherwise the operating-system default route is used.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Useful next comparison: Choose an output where the browser allows it, or change the operating-system output, then replay the same short tone.
Understanding the result
What a result means
The basic tone confirms that browser audio can start; the output selector appears only when a secure browser exposes sink selection. A missing selector is a support limitation, not proof that the speakers are unavailable.
Confirm the pattern by repeating audiocontext availability. Results reflect events and values exposed by this browser.
How to use this test
- Read the privacy and compatibility notes.
- Start the test and interact only inside the marked test area.
- Repeat the action several times and compare the live indicators.
- Use the troubleshooting section before deciding that hardware is faulty.
What this test checks
- AudioContext availability
- Short test tone
- Output selection capability
- Playback stop
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
Output selection requires HTTPS, permission and browser support.
Common problems and troubleshooting
First verify ordinary playback, then grant any requested device permission before selecting a sink. If a selected output remains silent, check the operating-system default and repeat without explicit selection.
- Repeat the same observation. Focus the test surface and repeat “AudioContext availability” three times under the same conditions.
- Change one condition. Compare “Short test tone” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
Audio output selection support is narrower than Web Audio playback and is feature-detected at runtime. Browsers without setSinkId continue to use the system-selected output and are labelled accordingly.
