No sound and no boot without usb key z77x-up4 th

[manusapo]

Hi everybody,
I am fairly new to the Hackintosh community. I searched through the treads and did not find the answer to my problem. I built a fully TonyX86mac Model

Z77X-UP4TH
i7 3770K
32 gb Ram Vengeance
GTX 680 graphic card ( Gigabyte )
256 gb SSD from Samsung
TP-LINK Wifi 4800

- The installation has two major troubles.

- I have no sound and it is impossible to boot the system without a USB key plugged on the PC.

- Minor issue : Overclock is not working. We tried on my friend's Z77X-UP5TH and it worked.

Do you gentlemen have any ways to solve this ?

thank you
Emmanuel

I found the sound solution. The good driver is : in MultiBeast 5.4 or newer - Select-Drivers & Bootloaders-Drivers-Audio-Realtek ALC8xx-Without DSDT √ALC892
