Is the result different with High Sierra?

Note: You might try enabling FakePCIID_Intel_HDMI_Audio.kext. Look in your model specific SSDT for RM,disable_FakePCIID, change the 1 to 0.

Also, layout-id=3 is another choice you can test (you can change it for testing with kernel flag alcid=3)

neither internal speaker nor jack work.

BTW, I find someone with the same model shared his CLOVER data. there's a section in his SSDT , which doesn't exist in mine, not sure why there is such difference, I've tried to add below section into my SSDT, nothing different:

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Same as above.

It was removed due to using AppleALC.
Note that "//CodecCommanderProbeInit" does nothing, as CodecCommander only looks for "CodecCommanderProbeInit".

Clear, thanks.

when setting disable_FakePCIID to 0, and layout-id to 3, I got attached debug report.

Your ioreg still shows layout-id=13 (look at HDEF.alc-layout-id in IOService, and IOACPIPlane.HDEF device-properties).

Note: It is easy to override layout-id that AppleALC uses by using kernel flag: alcid (eg. alcid=3)

I might misunderstand your meaning when generating previous report:
debug_disable_FakePCIID_0.zip keeps layout-id=13
debug_ID3.zip keeps disable_FakePCIID=1

now I combine them (disable_FakePCIID=0 & layout-id=3), as attached.
when headphone plugged in, it won't appear as the output option in sound setting, it appears as line-in input option.
neither speaker nor headphone works

So layout-id 13 is best for your audio?

I'd say yes, the jack works at least.

anything I can do to make the internal speaker work ?

You could try importing the XML we used for your model (branch 'archive', Resources_ProBook) into AppleALC under a new layout-id. Then test.
