No sound on laptop

No sound often means your laptop is sending audio to the wrong output device or a control is muted. Run the speaker test first; nothing leaves your device.

What the speaker test checks

The speaker test plays sound through the selected output device and checks whether the page can detect it. Listen for the test sound, then check the result shown on the page. A detected sound means the output worked during the test; no detected sound means the laptop may be muted, disconnected, using another output, or affected by a system problem.

The test can narrow down the issue, but it cannot identify every cause by itself. If you hear sound in the test but not in one app, the problem may be that app's volume or output choice. If the test detects no sound, use the case shown on the page to choose the next checks.

Tell which case you have

Run the speaker test linked on this page. If it reports NotFoundError, the selected output device could not be found. Follow the NotFoundError steps shown on the page to choose an output, set the default playback device, or address the audio driver.

If the result is general, the test did not identify a missing output device. Follow the general steps shown on the page to check mute and volume controls, connections and power, app settings, device status, sound settings, audio services, and system updates. These checks cover common reasons sound may not come through even when an output device is present.

Why laptop sound stops

A laptop can send sound to an output you are not using, such as a different playback device. An output may also be unavailable or not set as the default. That fits the NotFoundError case, so check the device selection and driver steps shown for that case.

In the general case, sound may be muted at the laptop, app, or another volume control. A loose cable, no power, disabled device, audio enhancement, or sound format issue can also interrupt playback. System audio services or pending updates may be involved, which is why the general steps include checking those settings too.

What to do if checks do not help

Use the steps that match your test result, then run the speaker test again. If it detects sound, try the app where the problem first appeared. If it still detects no sound after the listed checks, the cause may need a repair or replacement assessment; the steps on this page do not include repair or warranty instructions.

Questions

Is the speaker test a hearing test?

No. It checks whether the selected output plays a sound the page can detect. It does not assess hearing or hearing health.

What does NotFoundError mean in the speaker test?

It means the selected output device could not be found. Check the output selection, default playback device, and driver using the steps shown for this case.

What does a general result mean?

The test did not report a missing output device. Check volume, mute, connections, app settings, device status, and the other general steps shown on the page.

Why can I hear sound in one app but not another?

The app without sound may be muted or may use a different output. Check that app's volume and the output choice, then run the speaker test to see whether the output works.

What if the test detects sound but my laptop still has no sound?

The output worked during the test, so check the app or content where you noticed the problem. Make sure its volume is on and that it is using the output you tested.

When should I seek repair?

If the listed checks do not restore sound and the test still detects none, seek a repair assessment. This page's steps do not include repair or warranty guidance.
