If you are getting RPC errors, then go to task manager and make sure realtek universal audio service is enabled on startup. Your post also didn't tell us whether your motherboard comes with oem uad drivers and how you installed it (must use installer i.e. setup.exe). Do you have a motherboard with legacy driver and you are forcing it to install DCH drivers? That doesn't work.
What has HDA got to do with anything?
Fireberd (a member of this windows 10 board) back in Windows 7 days (on the previous windows 7 forum) had already figured it out that the reason why his gigabyte's realtek hd audio manager didn't have a 10 band EQ was because his gigabyte got soundblaster app which has the equalizer.
Realtek HD Audio: Equalizer not working properly - Windows 7 Forums
This is not new. It's been around for 15 years. It has nothing to do with HDA vs DCH drivers. If they give you 2 separate EQ then you will mistakenly enable both EQ at the same time and ruin your sound. This "there can be only one" rule is super simple to understand. If you have a premium audio computer, then the stock realtek EQ will be deleted and you have the premium EQ instead. Stop you rant about this simple to understand issue that will never be changed.
