Sorry for confusion. It's my first time to hackintosh. The audio ALC 255 is detected correctly, but no sound. At first, I don't know what kind of reason is relevant to the issue (maybe HD530 and the undetected hdmi codec). I search the forum, but no similar solution to the dummy of the detected...
audio_codecdetect.command shows the result:
HDMI audio codec(s)
Onboard audio codec
Device: Not supported
I google the HDMI codec 0x80862809, and it's codec ID for Skylake display audio codec. Is the codec id supported for hackintosh currently?
Thanks again for the help.

For the 10.11.4, I have add the dummyHDA fix line to the patched AppleHDA, according to [fix]10.11.4...
[Resolve boot screen garble] saves my HD 530.
But it shows some defects at the top-left of the Figure below: right apple bar disappears, but still click-available.
Mod the DVMT pre memory to 0x3, the problem is solved. :headbang:
Thanks so much for this amazing Mac.
As the update of 10.11.4, the HD 530 seems be fully working. For me, I try many settings like (Inject/intel, ig-platform-id) and patch in hd530 full works, but all fails for my HD 530.
I should miss a step of modifying the DVMT memory before installing the OS X. As mentioned in the...
