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.
