Missed a step, edited the post. Had to patch SSDT.

Although the audio issue has been solved, but I have another problem - USB issue... My USB cannot connect to an external hard drive properly. I don't know how to fix it...

@eddie1, please update your profile (personal details) with your Motherboard, CPU and iGPU or Graphics Card(s).
If you have a prebuilt computer enter make and model instead of motherboard.

Thanks, I was update my profile already.

I hope I can find out why the USB device cannot working correctly, so I reinstall my High Sierra today.

I found that the problem with USB is caused by incorrect config.plist settings, but I can't find why... so I will attach my config.plist as below, hope someone who can help me find the reason.

In addition... The new High Sierra audio after reinstallation still can't be find.... I used my old config.plist, and install kexts, but it didn't work :
