Hi ,
I understand your situation. Check if the sound icon has a white or red x. If it's white, click the icon in the taskbar at the bottom left. Click the icon again to activate the sound.
If it's red, follow the steps below:
Select Start > Settings > System.
- Scroll down and select Troubleshoot > Other troubleshooters.
- Go to Audio section and click the Run button to start the audio troubleshooter.
Give feedback if the information was useful or not.
Thanks
