To test sound on a computer, select the intended output, unmute the system and browser, lower the volume, and play a short left/right signal. If it is silent, check the connection and compare another output before changing drivers. Windows 11 keeps output selection under Settings → System → Sound.
Check your stereo channels. A few seconds is all it takes.

Ready when you are. Choose a test to begin.
Headroom OK
Start with your device volume low. 50% here does not guarantee a safe listening level.
No sound, or only one side? Let’s troubleshoot +
Check the selected output in your system sound settings, unmute this tab, and reconnect your cable or Bluetooth device. Turn off mono audio to hear channel separation. Still unsure? Try another pair of headphones.
A SIMPLE START
How to run this audio check
01
Select the actual playback device
In Windows 11, open Settings → System → Sound and choose the intended output. A connected monitor or receiver may be selected instead of your speakers.
02
Check mute and play a reference
Confirm the device has power and the browser is not muted. Begin quietly, then press Left speaker and Right speaker below.
03
Compare another path
Try the same output in another app, then another headset or speaker on the computer. This separates an app-specific problem from a broader device issue.
Start with output selection and volume
A computer can list several playback devices: built-in speakers, a USB headset, HDMI audio, and Bluetooth headphones. Choosing the right one is more useful than increasing volume on the wrong one. Confirm that your selected device is the physical device you expect to hear, then check the system and app-specific volume controls.
Microsoft’s Windows troubleshooting guidance begins with output selection and connection checks. If a monitor appears as the output but has no speakers, select another device. If the intended output is missing entirely, investigate its connection and recognition before interpreting a silent browser test as a speaker fault.
Separate a browser issue from a computer issue
Play another familiar source through the same device at low volume. If only one browser tab is silent, look for tab or site mute controls. If the browser works but a meeting app is silent, compare that app’s device selection. The website cannot change system settings or force another application to use the same output.
If multiple applications fail on the same output but another headset works, the result narrows the problem to that device or connection. If every output fails, use the operating system’s audio troubleshooting tools and the hardware manufacturer’s guidance. Avoid installing an arbitrary driver download solely because a web test is silent.
Diagnose unbalanced or distorted computer audio
Use the same left/right signal on both channels and sit consistently between speakers. Check balance and mono audio if a side is weak or the channels merge. A partly inserted analog connector can create confusing symptoms, so lower volume and reseat it before repeating the test. Keep optional effects unchanged while comparing.
For a buzz limited to certain pitches, the Hz tester offers a more focused next step. For delayed sound on wireless headphones, use the headphone sync comparison. Neither result establishes a driver diagnosis by itself. Write down the exact trigger, output device, and whether another app behaves the same way before asking for support.

The tool behavior described here reflects this website’s implementation. These primary references explain relevant browser capabilities or equipment and application settings.
Open Settings, then System and Sound, and choose the intended output device. Check system and app volume, lower the listening level, and play the left/right signals here. If there is no sound, check power and connections, then compare another application or output to narrow the problem.
Why is my computer sound test silent?+
The output may be muted, disconnected, unpowered, or routed to a different device such as an HDMI monitor. A browser tab can also be muted independently. Verify those settings first. Compare another known audio source and another output before concluding that the speakers or driver have failed.
Can this test repair my Windows audio driver?+
No. It supplies repeatable playback signals and troubleshooting guidance but cannot inspect or replace drivers. Use your operating system’s troubleshooting tools and the device manufacturer’s official support when needed. A silent browser test alone is not enough evidence to identify a driver fault or choose a replacement.
Why does only one computer speaker play?+
Possible causes include balance settings, a loose connection, channel routing, or a hardware problem. Test left and right separately, center the balance, and reseat the connector at low volume. Compare another output on the same computer to see whether the symptom follows the speaker or remains with the source.
