how to fix sound audio issues on window 10

Use the built-in troubleshooting steps in Windows 10 to diagnose and fix most audio issues.

1. Check sound settings and mute state
   1. Right-click the Speakers icon on the taskbar and select Open Volume mixer.
   2. Make sure none of the volume sliders are muted or set to 0. If muted, select the volume control to unmute.
   3. Open Start > Settings > System > Sound.
   4. Under both output and input, select the device in use and choose Device properties.
   5. Ensure the Disable checkbox is cleared for both output and input devices.
2. Set the correct default audio device
   1. In the search box on the taskbar, type control panel and open it.
   2. Select Hardware and Sound > Sound.
   3. On the Playback tab, right-click the speakers/headset or other device that should play sound and select Set as Default Device, then select OK.
   4. If an external monitor without speakers is set as default, change it to the actual speakers/headphones.
3. Verify Windows Update and restart
   1. Go to Start > Settings > Update & Security > Windows Update > Check for updates.
   2. If updates are available, select Install now, then Install.
   3. Restart the PC and test audio.
   4. If the Start > Power menu shows Update and restart or Update and shut down, choose one of these to apply pending updates.
4. Update or reinstall audio drivers
   1. In the search box, type device manager and open it.
   2. Expand Sound, video and game controllers.
   3. Right-click the sound card or audio device (for example, speakers/headphones) and select Update driver > Search automatically for updated driver software. Complete the wizard and test.
   4. If no newer driver is found or audio still fails, right-click the device again and select Uninstall device.
   5. Check Delete the driver software for this device, then select Uninstall.
   6. Restart the PC so Windows reinstalls the audio driver automatically.
5. Use the generic Windows audio driver (if vendor driver fails)
   1. Open Device Manager and expand Sound, video and game controllers.
   2. Right-click the audio device and select Update driver.
   3. Select Browse my computer for drivers > Let me pick from a list of device drivers on my computer.
   4. Select the audio device driver from the list, choose Next, and follow the prompts to install it.
6. If audio broke after a Windows update
   1. Open Device Manager and expand Sound, video and game controllers.
   2. Right-click the audio device and select Properties.
   3. On the Driver tab, select Roll Back Driver (if available) and follow the instructions, then select Yes to confirm.
   4. If rollback is not available or does not help, use a system restore point created by Windows Update as described in Recovery options in Windows.

If these steps do not resolve the issue, install the latest audio driver directly from the PC or motherboard manufacturer’s support site and test again.
