I have the same motherboard, and have it now working pretty well thanks to some of the info in this thread. A couple of things that may help anyone else with the same board:
For the USB to work, all I did was to follow step number 2 from post #2 on the thread below, nothing else, and now it seems to work, full USB 3 speed on all relevant ports:

For the sound I just used Kext Beast to install this guy's kext (post #1) and now sound output from the green port works great, also after sleep:

I also am dual booting windows 10, but from the same SSD. It took a while but I got it to work. For clover to pick up the windows 10 install you have to make sure windows is installed to a GPT/GUID partition. I followed this thread:
