Windows 10: "No Audio Output Device Is Installed" after updating from Windows 7 to Windows 10

Two days ago I upgraded my old pc from Windows 7 to Windows 10 and ever since my speakers doesnt work, tried updating the drivers, downloading new audio driver, reinstalling the windows, the system file checker but nothing works. When I go to Device Manager and open Audio Inputs and Outputs theres only Microphone and Line In but no Line Out.CPU:AMD Athlon II X2 250GPU:AMD Radeon R7 200 SeriesMotherBoard:ASRock N68-GS3 UCC

no audio output device installed

I've tried every step that was suggested, still getting no audio output device installed.

 

Unlocked Realtek HD Audio Drivers Windows 7 & 8 (With Dolby Digital Live and DTS Interactive)

I think today's windows update(stable channel) solves d issue

Cumulative Update KB4020102 Windows 10 v1703 Build 15063.332

• Addressed issue where, after installing the Creators Update, audio output through external decoders no longer works.

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
