So after Microsoft sneakily updated my windows without my consent,

All my media player files stopped playing sound, my media players also does not appear in the audio mixer at all.

I mentioned only media files because other audio seems to work fine, windows notification sounds plays fine, video on Youtube via chrome browser also work fine,

Movies will play fine, but without audio, if I try to play a file in Windows Media Player, it will show the following error message

"windows media player encountered a problem while playing the file"

I have tried:

Updating Realtek audio drivers
Uninstalling/reinstalling Realtek audio drivers
Installing different versions of Realtek audio drivers
Disabling/re-enabling "Windows Audio" Service.
Updating motherboard drivers

All will not work, but if I uninstall the Realtek drivers completely and let windows resorted to install its built-in "High Definition Audio Device", all audio would work properly but with degraded sounds as usual.

Specs: MSI Gaming M5 motherboard, Realtek® ALC1150 Codec.

Any help would be greatly appreciated! Thanks in advance.

i guessing you using UEFI booting, right?

Yes, is that a problem?

get latest driver.

already did. :|

but I end up doing a clean install and solved the problem, really hate M$ and their forced upgrade, wasting my time doing backup and reinstall.

It's older than my stock win10 driver.

You can grab the latest drivers here:

in fact I have tried a few latest ones until I finally took my time to backup and reinstall the OS.
