Hi,

I'm sure the answer is obvious but worried to try:

Windows 10 OS using NVidia graphics and Realtek sound.

This morning after a windows update ran , I have no sound. Troubleshooting shows that a solution maybe to reinstall 2 drivers from Realtek and NVidia. I tried the Auto fix solution but problem persists.

On the Device Manager it is showing an orange warning triangle on both drivers, saying reinstall. Code 18. As I said the Auto update install does not rectify the problem

Can I safely uninstall the drivers ? And then how do I reinstall them ?

 

Thanks in advance

Is this an OEM system or a custom build?

This determines where you'll get the drivers from.

 

In short, you'll download fresh copies of the latest W10-compatible video and audio drivers.

Then you'll uninstall the current video and audio drivers.

Then you'll install the freshly downloaded drivers.

That should fix the problems.

 

If it doesn't, post back for further suggestions.

My Realtek HD Audio driver also broke thanks to that cumulative update.
I was not able to update it by Fix it nor in Device Manager - I kept getting continuous error 0x5B3.
Before installing a new driver, I uninstalled it according to directions Lenovo provided.
I did not get a chance to install the new driver, since it got replaced by Microsoft's "High Definition Audio Device". Totally surprising. I don't think I clicked anything to trigger it, but am not 100% sure.

That new, unexpected, driver is working fine.

I wonder if this unwanted trouble might be related to this item in the M$ description of thie update:
"Fixes audio playback problem with music apps on a phone "

Except my laptop is not a phone :( and I have no idea what's going on.

"If it ain't broke, don't fix it."

If you have further problems, download drivers from the Lenovo support site for your system.

But otherwise, just leave it alone if it's working well.

 

Good luck!

Thanks for the replies.

I downloaded the drivers, which were in fact exactly the ones I had.

Before uninstalling the "old" ones, I "disabled" the 2 drivers which were flagged up as problems, and rebooted.

Windows detected that the drivers were disabled and asked if I wanted them enabled.............replied yes. Rebooted.................and everything working again.

 

Thanks again though for your help and support
