dsdt does not have device HDEF, required for OS X audio. Install this ssdt: https://github.com/toleda/audio_ALCInjection/blob/master/ssdt_hdef/ssdt_hdef-1-no_ioreg:hdef.zip If BIOS is 3xxx, no AppleHDA audio; 2xxx works as expected.

Apologies for the delay. See https://github.com/toleda/audio_ALCInjection, add HDEF.

macOS does not support 100 Series HDAS. Fix: install https://github.com/toleda/audio_ALCInjection/blob/master/ssdt_hdef/ssdt_hdef-1-100-hdas.zip

@amark89 macOS does not support 100 Series HDAS, see ssdt fix above.

See https://github.com/toleda/audio_ALC_guides/blob/master/Realtek%20ALC%20AppleHDA.pdf Unsupported/Non-working Realtek ALC AppleHDA 4. 888_v100201 and earlier

888_v00001, not supported.

if the Legacy workaround does not work, there is no other solution. Resources limited to codecs I own, no chance it will be added.

Apologies for the delay, 10EC0888 is hex.

See README/F. Problem Reporting Attach requested files.

Screenshoot shows no codec. SSDT-HDEF.aml is not correct, remove. Install https://github.com/toleda/audio_ALCInjection/blob/master/ssdt_hdef/ssdt_hdef-1-100-hdas.zip Restart, reply with new files; include IOReg.
