Windows 10 install, NO Sound

Hey Folks,

i have a "MacBook pro early 2011" (MB101) // MacBook pro8,1.

well i installed Windows 10 for dual boot. Everything is fine and the System works great, but the only Thing which wont work is the Sound Module.

Tested about 1000 Drivers but no matter what i do the Sound wont work.

It must be the "Intel HD high Definition Audio" Interface but i cant fix this Problem.

The Intel Software Updater says there is no update to do, another realtek high definiton Driver says, that

"Microsoft Bus Driver should be loaded in your System before installing Realtek HD Audio Driver!"

Anyone had same issues ? i really hope you guys have a solution to fix this.

Thank you...
