Windows 10: Failed to Play Test Tone -> Never Solved

HP Recommended
HP Pro 3130 Microtower PC
Microsoft Windows 10 (64-bit)

I've tried everything there is to fix it.

 

PC crashed one night, and then after reboot, my sound is gone. I can see the Sound icon on the task bar, I can increase-decrease sound volume, just NO SOUND. Whenever I try to "TEST" my current hardware (say I use Headphones), I only get "Error! Failed to play test tone".

 

Several fixes on the internet, I've tried them ALL.

 

Sfc/scannow -> No integrity problem found.

Services -> Restarted Windows Audio -> Several times

Registry -> Gave Local Machine Admin access -> No dice.

Chkdsk, etc -> Nada

Uninstall / delete / burn / kill etc. Drivers for Nvidia & Realtek High Definition Audio -> Nope.

Properties / Advanced / change default format (whatever I put there) -> "Error! Format not supported by the device".

 

Strangely enough, when I uninstall the drivers, they seem to AUTO-reinstall, as in I do scan for hardware changes and it doesn't ask me what I want to do, they're reinstalled in a matter of 5".

 

Also, when I check the driver details, and I get say "C:windows\system32\drivers\hdaudio.sys, I can't delete this file, either as admin, or as elevated cmd & Delete, or even after allocating ownership to my own name.

 

Need I go to safemode just to delete this file, and have windows 10 find it again? Dunno.

 

Guys, I've spent more than 4 days straight, trying to fight that, nothing works.

 

I need something else.

 

I will only reformat the pc as a last resort, my son has tons of games in it, I'm afraid I'll lose 50% of that, and my software as well.

 

Thanks in advance,
