There is no sound from this PC

No sound does not automatically mean the speakers have failed.

Windows can have several outputs at once: built-in speakers, headphones, Bluetooth devices, docks, or HDMI/DisplayPort monitors. Sound may simply be going to a device you are not listening to.

The first question is:

Does Windows see the output device you intend to hear?

Check where Windows is sending the sound

Open Settings > System > Sound and look under Output.

Select the speakers or headphones you actually want to use and make sure the volume is not muted. Microsoft lists an incorrect output device and muted sound among the first causes to check when no audio plays. [R1]

This is especially important after connecting a monitor, dock, or headset. If selecting the correct output restores sound, there is no reason to reinstall the driver.

Is the output device missing completely?

A different problem exists when the expected speakers or headphones do not appear under Output at all, or Windows reports that no audio output device is installed.

Microsoft documents that Windows may fail to detect an output device when the audio driver is missing, outdated, disabled, incompatible, or not loading correctly. [R2]

Open Device Manager and check Sound, video and game controllers. Microsoft recommends confirming that the audio device is enabled and detected there. [R2]

If an external device is missing, also check its cable, port, power, and physical controls before treating the problem as a Windows fault.

If the device exists, check whether Windows audio is running

Windows relies on background services to provide the audio path.

Microsoft's Windows audio troubleshooting procedure specifically identifies Windows Audio and Windows Audio Endpoint Builder among the services to restart when sound problems continue. [R3]

If one of these services has stopped or failed, a perfectly healthy speaker and driver may still produce no sound.

Restarting an audio service can restore a temporary failure, but repeated service failures need separate diagnosis rather than repeated restarts.

Is every application silent?

This article is for system-wide sound failure.

If Windows system sounds or other applications still produce audio, but one program is silent, the output path itself may be working. Microsoft documents separate per-application volume and output-device settings in the Windows Volume mixer. [R4]

In that case, check the affected application's volume and selected output rather than changing the whole system.

What about audio enhancements?

If the correct output device is present, enabled, selected, and still silent, Microsoft also lists audio enhancements as a possible cause and recommends testing with them turned off. [R1]

Test this separately so it remains clear which change affected the problem.

When should you change the driver?

Driver work becomes more relevant when Windows does not detect the output device, the device disappeared after an update or driver change, or the device remains unusable after output selection, volume, service, and connection checks.

Microsoft recommends Windows Update as the first way to obtain current audio drivers. [R5]

If Windows Update does not provide a suitable driver, Device Manager and the manufacturer's support site are the documented follow-up paths. [R5]

What should I do now?

  1. Open Settings > System > Sound and select the output device you actually want to hear.
  2. Make sure the output is not muted and the volume is high enough to test.
  3. If using external speakers or headphones, check the cable, power, port, and physical controls.
  4. If the expected output is missing, check whether Windows detects and enables the audio device in Device Manager.
  5. If the device exists but all sound is still absent, check the Windows audio services.
  6. If only one application is silent, check that application's volume and output device instead of changing the whole system.
  7. If the correct device is present but still silent, test with audio enhancements disabled.
  8. Investigate the audio driver only after the earlier checks identify detection or driver state as a plausible cause. Use Windows Update first.
  9. If Windows still cannot detect a known-good audio device after appropriate driver and connection checks, test another output device or port where possible to separate software failure from hardware failure.

The goal is to determine whether sound is failing at the selected output, device detection, Windows audio service, driver, or physical hardware layer and repair only the layer that is actually broken.
