Maybe it is time to start from scratch. What you can do:
- remove all unnecessary hardware including graphics card
- reset bios/uefi settings to default
- install some linux distro (or boot from live medium) and test sound
- install clean windows, retain generic hd audio controller driver and test sound
If this bare system works ok, you can one-by-one add hardware & install device-specific drivers and software; test the sound quality after each step.
