I didn’t find how to disable 225v in the BIOS. When the iGPU was turned off in the BIOS, Audio was also turned off there, but when booting from Win PE, they are still in the system. The Win7 image proposed here ([Solution] Win7/8.1 Drivers for USB 3.0/3.1 Controllers of new AMD Chipset Systems) behaves the same way.
Help solve this problem. I’m sorry for the bad English
