Via audio driver doen't working anymore after windows update.

After updating latest windows 1709 my audio driver broken.
At first i thought sound enhancement feature called "Speaker Fill" didn't work.But when i play multi-ch audio only two speaker is working & other are mute.
My motherboard is Asus p7-H55-mlx/usb3.
I contact with Via audio in their facebook page.
They told me they won't update their driver anymore.
Interesting fact+shocked is in they are driver portal page they won't provide audio driver for windows 10 anymore!

yeah via is really bad at providing support for their devices...sometimes taking years before providing updated drivers.

Hi, compatibility isn't maintained for ever. My cooker works, but I can't get most of the parts should I need to.

What was the last OS you had installed? Did you upgrade from the Creator's build or something earlier?

I suggest two possible options with your current PC.
1. Revert to your previous build (you have 10 days from upgrading). You would then have to take action to stop a future upgrade (Tutorial available in the Tutorial section).
or
2. By way of an outside chance try a driver scanner program (which we wouldn't normally suggest and certainly not routinely).
E.g. DriverMax (2 drivers free per day with the free version)

I know my mobo is old.But Via audio they provide driver for windows 10 which is work till last update i mean 1703.What should i do now?As i said 1st i thought only Sound Fill is not working that's why i reinstall my driver.But before reinstalling driver multi-ch audio was worked.And Via software can be found in my start menu as well as it can be also opened.But now i can't find it anywhere besides Uninstalling apps.

- that's with your current configuration/build.

I installed the DriverMax.It shows my audio driver was update.
How can i rollback to last update?
As you said i have 10days.So i have been waiting till last date for finding the solution in the internet.

Thanx

Just fixed it by myself.

How?
