[Help] Various problems with Sierra

Hello, I just installed Sierra 10.12.6 using unibeast, all went well, no problems whatsoever, I booted into the OS, GPU is working correctly(AMD R9 270X Sapphire 2GB), I get no graphical glitches, no abnormalities, everything seemed to be in order.

Then I tried to see if audio was working, and to no one's surprise, no, it wasn't. I then ran MultiBeast and checked "VoodooHDA 2.8.8" along with "Generic USB 3.0" which also doesn't work.

So to summarise, I got no audio, front panel USB 3.0 doesn't work, I'm missing my /System folder, I can't boot without USB.

Thanks in advance :)
