Anything on 10.13 High Sierra audio yet?
 
Hi,
Can someone explain what means first digit of verbs (Codec Number) ?
f.e. "21471C10 21471D40 21471E11 21471F01 21470C02" I change number "2" to "0" "01471C10 01471D40 01471E11 01471F01 01470C02" and my internal speakers work both ways. I ask because I see some codecs verbs start with "0" and some with "2". From what it depends, is it important to setup?

PCI address for the audio codec, example: 2.

Does this method work with the ALC255? Or changing some points from the guide. There's too little information about that codec... thank you for all your work!

Method works however nodes and pins are different for each codec. Different method with several 255 choices, Google search: AppleALC wiki

In audiocodecdetect it shows Layout ID=1 for the ALC255 (which is not valid). I followed the fix that appears in the terminal, but with no luck, it still shows Layout 1 instead of 3. I followed Skylake NUC6 guide from @RehabMan for my GB-BSi5-6200. Everything is working except the audio. I guess it's a thing about his patched DSDT? This is his repo https://github.com/RehabMan/Intel-NUC-DSDT-Patch/raw/master/config_install_nuc6.plist
