Below are the steps to fully check and enable sound on your computer, please follow step-by-step
Step 1: Run the Windows Audio Troubleshooter
Go to Settings → System → Sound → Troubleshoot. Alternatively, right-click the speaker icon in the taskbar and select Troubleshoot sound problems. This automated tool can detect and fix common audio issues.Step 2: Check Output Device and Volume
Click the speaker icon in the taskbar. Ensure the correct playback device (e.g., Speakers, Headphones) is selected. Verify the volume is not muted and sliders are up.Step 3: Restart Audio Services
Press Win + R, type services.msc, and press Enter. Locate Windows Audio and Windows Audio Endpoint Builder. Make sure both are running and set to Automatic. If not, start or restart them.Step 4: Update or Reinstall Audio Drivers
Press Win + X → Device Manager → Sound, video and game controllers. Right-click your audio device (e.g., Realtek, High Definition Audio) → Update driver. If updating doesn’t help, choose Uninstall device (check “Delete the driver software” if ailable), then restart your PC. Windows will reinstall the driver automatically. For best results, download the latest driver from your PC or motherboard manufacturer’s website.Step 5: Enable Disabled Devices
Right-click the speaker icon → Sounds → Playback tab. Right-click in the empty area → Show Disabled Devices → Enable any listed devices.Step 6: Test with External Devices
Plug in headphones or external speakers to check if the issue is hardware-related. If sound works externally, the internal speakers might be faulty.If the issue persists, try:
Rolling back drivers to a previous version. Creating a new user profile to rule out profile corruption. Running OEM diagnostics (HP: F2, Dell: F12, Lenovo Vantage).To assist others who might he similar questions and to help us improve our support system, we kindly encourage you to "Accept the answer" if it successfully addressed your concern.
