Hi Ali, thanks for reaching out. My name is Bernard, a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.
I understand the issue you have, there is nothing to worry I am here to assist. Was it working fine before? Or is there no audio at all? Are you using a laptop or a desktop? If you are using a desktop, kindly check if there is a speaker installed on the PC, Moreover, if it's working fine before, kindly follow the steps below:
Method 1. Run Audio troubleshooter:
Press the Windows Key + R, then type in:
msdt.exe /id AudioPlaybackDiagnostic
Then hit OK and follow the prompt to run the Audio troubleshooter.
Method 2. Roll Back Audio driver:
-Press the Windows key + X
-Go to Device Manager
-Expand the Sound, video and game controller
-Look for Realtek (R) Audio or High Definition audio
-Right-click and click "Update Driver"
-Look for "Browse my computer for driver"
-Click "Let me pick drivers available drivers on my computer"
-Choose an old driver or other name of driver then select it and hit next until it installs.
Note: If the issue persists, please download and install an Audio driver from your manufacturer's website.
Let me know how it goes and I hope that helps.
Bernard
