Use this check to inspect a browser, device, network, permission, media, or input capability directly in the current runtime before relying on it in another workflow.

Audio output probe

Audio output probe supplied by the surface.

Diagnose audio playback from an output probe covering rate, channels, latency, and underruns. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Verdict

Overall audio playback diagnosis.

Sample rate (Hz)

Output stream sample rate in hertz.

Channel layout

Named layout for the channel count.

Latency (ms)

Median observed output latency in milliseconds.

Underruns

Number of observed buffer underrun events.

Issues

Stable machine-facing degradation codes.

• Results describe the current browser session and can change with permissions, privacy controls, hardware, drivers, network path, power state, or browser updates. Unsupported or withheld information is not proof that the underlying capability is absent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Repeat the check in the browser and device that will actually be used, then confirm important behavior with the relevant operating-system or network diagnostics. Avoid granting permissions that are unnecessary for the test.

• Webcam Tester

  Diagnose a webcam from a captured frame probe, reporting verdict, frame rate, and resolution.

• Display Checker

  Analyze a display probe into refresh rate, resolution class, and pixel density estimates.

• Media Support Checker

  Summarize codec probe results into playback readiness with coverage and gaps.
