I have a very simple solution to fix no audio problem on your laptop. You can apply it on your device.
- First of all, you need to open the command prompt window.
- Type ‘Rstrui.exe’ and press enter button.
- Now you will be able to see system restore window, in this window, you need to click on the next button.
- Now choose the restore point, when your computer was working fine and click on the next button.
- Once you will see the finish button click on it.
After hitting the finish button, your computer will restore the windows settings to the previous date. When Audio was working fine.
Note- When you system restore your device. You may loose the windows update or app installed between during the time.
