Windows update seem to have screwed up my speakers

Today I had a update notification. I didnt read it full and click OK. But since then my speaker and headphones are refusing to play. I checked Windows update history, and the update installed today is titled "2021-09 Cumulative Update for Windows 10 Version 21H1 for x64-based Systems (KB5005565)" with this link.

Since, then I have tried fiddling with drivers, but no help. When I right click on the device and click Test, it says "Failed to Play test tone":

I uninstalled and reinstalled devices several times. Every time, this is what the device manager says "This device is working properly":

Intel Driver Support Assistant did not suggest any audio driver:

Also when I tried to run IntelAudioService.exe by typing in start menu, it gave me following:

Not to mention I am unable to listen anything from headphones too.

I am not able to guess what went wrong? Is system restore / clean Windows install only option left? Will system restore screw anything? Cant I just reinstall everything related audio? without doing system restore or clean Windows install?
