No sound from mini-jack on the rear panel of the Win 10, Mac Pro 1.1

Sorry for my english.

On your Mac Pro 1.1, install the Windows 10 x64. All devices were defined and work, in addition to the audio output mini-jack on the rear panel 3.5". Sound can be heard only from the built-in speaker.
Audio device drivers installed from BootCamp, that I have prepared on the same computer in Mac OS Lion.
How to get the system to send audio mini-jack?
Thanks for the help.

Empirically determined that Windows does not want to identify the rear panel.
When connecting the speakers to the mini-jack on the front panel of the sound appears. In the settings Realtek HD connection icon lights up to headphones.
You may need to physically disconnect the mini-jack and built-in speaker on the front panel. Then Windows (Realtek) starts properly output the sound to the rear panel.
