Lenovo Flex3 Audio Suddenly cut off

I was in the middle of wathing a College lecture and the audio suddenly cut out. The video kept playing but there was no sound. I did not hit a button or touch anything. All of the audio volume controls are on and nothing is muted.

I thought that it was maybe just my colleges site. But after trying to play videos from other sites as well there is no audio coming from any of them.

There is also no audio when I input headphones into the jack either. So I gather that the problem is not the speaker and is something else.

 

Any help would be amazing

Thanks

Re: Lenovo Flex3 Audio Suddenly cut off

Hi there, Jcoy  -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

STEP1:   Reinstall Audio driver

 

  1. Uninstall the Realtek HD Audio Driver from the Control Panel (large icon view) > Programs and Features and reboot
  1. After the reboot, Windows will now install a generic sound driver (High Definition Audio). Try to re-create the issue that you're having and observe.
  1. If using the generic sound driver fixes it, try re-installing the audio driver from theD:\Drivers\Audio folder or from this link:

Realtek Audio Driver for Windows 10

Realtek Audio Driver for Windows 8.1

Realtek Audio Driver for Windows 7

 

STEP2:   If Steps 1 does not work, Uninstall KB2962407

 

Go to “Control Panel” > “Windows Update”, View Update History. 
Select Installed Updates. If KB2962407 is installed, please right-click the update to uninstall

 

STEP3:   Hardware inspection

Contact Lenovo service center and report your findings for hardware inspection.

 

Update us how it goes.
