- Device & OS
- Windows
- Scenario
- Attempting to play media or system sounds through external or built-in speakers but hearing no audio.
- Observed behavior
- No sound is produced from the speakers even when media is actively playing and the system volume appears to be turned up.
Before altering system settings, verify that your speakers are physically connected to the correct audio jack, powered on, and the volume knob is turned up. Also, try testing the speakers on another device like a smartphone to rule out hardware failure.
Verify Output Device and Volume Settings
Use this solution to ensure Windows is sending audio to the correct speakers and that the system sound is not muted.
Often, Windows may default to a different audio output, such as a connected monitor or headset, causing your main speakers to remain silent.
Click the speaker icon on the Windows taskbar. Click on the current audio device name to open the list of output devices, and select your preferred speakers.
Right-click the speaker icon and select 'Open Volume mixer'. Ensure neither the main system volume nor the specific application you are using is muted or set too low.
Press Windows + R, type 'mmsys.cpl', and press Enter to open the Sound control panel. In the Playback tab, right-click your speakers and select 'Test' to see if a chime plays.

Run Audio Troubleshooter and Update Drivers
If settings are correct but sound still fails, use the built-in troubleshooter or Device Manager to fix underlying software conflicts.
Restart Windows Audio Services
Sometimes background audio services crash or stop running, completely muting the system. Restarting these services can restore sound instantly.

Frequently Asked Questions
Why does my volume mixer show sound is playing but I hear nothing?
This usually means Windows is routing the audio to the wrong output device (like a disabled monitor speaker) or that there is a physical disconnection between your PC and the speakers. Verify your default playback device in the Windows Sound settings.
How do I check if my computer speakers are physically broken?
Unplug the speakers from your computer and plug them into another device, such as a smartphone, tablet, or another PC. If they still do not produce sound, the speakers or their audio cable may be defective.
What is the Windows Audio Endpoint Builder service?
It is a core background service in Windows that manages audio devices. If this service is stopped, corrupted, or disabled, all audio devices (including speakers and microphones) will fail to function properly. Restarting it via 'services.msc' often fixes sudden sound loss.
Can outdated Windows updates cause my speakers to stop working?
Yes, missing critical system updates or conflicting audio driver versions can break sound functionality. Going to Settings > Windows Update and installing the latest updates can often install the necessary patches and driver fixes automatically.
