How to Fix "No Output Device Found"
You may encounter the "No Output Device Found" issue on your computer. This guide offers solutions to restore audio functionality.
1. Update Audio Drivers
Outdated or corrupted audio drivers can cause the device to go unrecognized. Updating the drivers promptly can effectively resolve this issue. Using Driver Sentry is recommended for automatic detection and updates, saving time and avoiding errors.
Download the latest version of Driver Sentry, install, and open it. Click "Scan".
After scanning, the tool will list missing or outdated drivers. Locate the audio driver and click "Upgrade".
Restart your computer after updating to ensure the changes take effect.
2. Check Hardware Connections
If using wired headphones or speakers, ensure the plug is securely connected to the audio jack.
Check for damage or looseness in the cables.
Try different audio ports (e.g., front or rear panel) if multiple are available.
For Bluetooth headphones or speakers, ensure the device is properly paired and the Bluetooth function is working correctly.
Use compressed air or a small tool to gently clean dust from the audio jack to prevent poor contact.
3. Verify Audio Devices Are Enabled
Open "Sound Settings" or "Open Sound Settings".
Under "Choose Your Output Device", ensure the correct audio device is selected.
Press Win + X and select "Device Manager".
Expand "Audio Inputs and Outputs", and check for any disabled devices (indicated by a downward arrow).
If a device is disabled, right-click it and select "Enable Device".
4. Restart Audio Services
Press Win + R, type "services.msc", and hit Enter.
In the Services list, locate "Windows Audio" and "Windows Audio Endpoint Builder".
Right-click each service and select "Properties". Ensure the Startup Type is set to "Automatic".
If the services are not running, click "Start".
Click "OK", then restart your computer.
5. Repair System Files
Press Win + S, search for "cmd", right-click Command Prompt, and select "Run as Administrator".
Run the SFC Tool: sfc /scannow
Wait for the scanning and repair process to complete.
Run the DISM Tool if the issue persists: DISM /Online /Cleanup-Image /RestoreHealth
Restart your computer once the process is complete.
