HDMI Audio not working - Intel 630

Hello,

I couldn't get my HDMI Audio working
TIA

Procedure
1. Mount EFI
2. SIP enabled, OK <-- No idea what this mean
3. Intel: HDMI display only
4. Double click: Downloads/audio_cloverHDMI-1... command

Result
File: audio_cloverHDMI-120.command_v1.0d
Release Mode
EFI partition is mounted
Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem
Continue without HDEF/onboard audio (y/n):

Expected Behavior
Will detect onboard audio first?
