Audio Not Working After Windows 10 Version 2004 Update

Hi C. I'm Greg, an installation specialist, 10 years awarded Windows MVP, and Volunteer Moderator, here to help you.

I'll give you all possible solutions for Sound problems in order of priority, so please try any you've already tried again in order. If you have any problems performing any steps I'll be standing by here to help you.

If this was caused by a Version Update then for 10 days you can roll it back in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool which is explained more here:

If that doesn't work you can also Go Back in Repair Mode as shown here:

All other fixes for sound problems in Windows 10 here. Even if you've tried one please try it over in this sequence. Please don't skip any steps. We often find out later that the fix was the skipped step. If you need help performing any step I will help.

1. Update the sound driver from the PC or device maker's Support Downloads webpage for your exact model, if it is newer than the one presently installed in Device Manager reached by right clicking the Start button. While there compare to make sure you also have the latest BIOS, Chipset, Display, Network and all other drivers.
2. Next try this checklist: https://support.microsoft.com/tr-tr/help/402699...
3. Right click Volume icon in System Tray, choose Sound Settings, from the Output and Input devices dropdown menus, choose then one(s) affected to see if that helps. If not use the Troubleshoot button nearby.
4. Run the Playing Sound troubleshooter at Start button > Settings> Update & Security > Troubleshoot.
5. Try rolling back the sound drivers in Device Manager reached by right clicking the Start button. Choose Sound controller and other audio devices, then Driver tab, then Roll back if available.
6. If no newer sound drivers then uninstall the one presently installed in Device Manager, reached by right clicking the Start Button. Restart PC to reinstall.
7. Try other and older drivers for your model Sound controller, too. For example, try the next oldest driver in the model's online Support Downloads list. To try all previous drivers installed on your system, in Device Manager choose Sound controller's Driver tab, then Update Driver, then Browse, then Let Me Pick.
8. Finally, try installing the latest Sound driver in Compatibility Mode as shown here:

9. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/tr-tr/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

10. If nothing else helps then run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This solves many problems and will also bring it up to the latest version which you need anyway and by the most stable method. http://windows.microsoft.com/en-US/windows-10/m...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

The HDMI audio on the HDC G2 mini PC also stopped working with the Windows 10 2004 update.

Intel released a driver that fixed the problem for the previous Windows 10 update, but that driver will no longer install at all and says "this computer does not meet the minimum requirements".  The driver file name is win32_15.33.50.5129.

The processor is an Atom Z3735F.

Also dragging the Window of CPU-Z with my mouse acts really strange.  I'm going to try reverting back to the previous version of Windows.

I have the same issue and nothing is working to resolve the "no sound" problem with Windows 10 upgrade

Yes.... I am still stuck with it .... although now getting ready to reset the PC or else no Zoom meetings ... and still no idea if I can get it repair as mine was upgraded from Windows 8 to Windows 10 .....

It was very irresponsible on the part of the Microsoft Team to push out the update.

I solved it by uninstalling the device. Removing all realtek driver folder and program .. folders. Then when I 're booted the machine the generic windows audio driver got installed.
