Random issue with sound on Window 7 laptop

[BetaTime]

Hi guys,

 

I have an issue with one of my laptops at home. Randomly (but quite often) there is no sound when I move the "sound cursor" in the speaker tray(and of course there is no sound at all when playing videos or MP3...). The sound is not muted, all is

fine when we go to the control panel (no errors), but when we want to TEST if the sound works, we don't hear anything. The workaround is simple, I go to the devmgmt.msc and disable then enable the "REALTEK HD Audio device" and the sound is fine then.

 

But as a system admin I would like to find a permanent solution, in case I have a similar issue with my users at work.

 

What steps I have already done:

 

- update REALTEK HD Audio driver with the latest driver available in their website (2.82).

 

- check with Process Monitor if something is wrong when I move the cursor and have no sound, but didn't found Nothing interesting.

 

- compared task manager processes when the sound is fine and when the sound is not working. But didn't find any diff?rences.

 

Informations: laptop is Lenovo X230, running W7 pro x64, all updates installed, all is working fine on this laptop excepted this sound issue. Nothing is plugged into the laptop (no headphones, no speakers, no docking station, no screen). I have the issue

for two month or so, all was fine at the beginning.(I need to find the real cause of the issue and not just do a system restore :) )

 

Thank you in advance for your help, Don't hesitate to ask complex things to try!
