HDMI Audio works only in verbose boot mode NVIDIA GTX 1080

I installed Macos HighSierra on this setup:
MB: MSI Z170A GAMING M9 ACK
CPU: Intel i7 6700k
GPU: Nvidia GTX 1080 Founders edition (with official web drivers)
Monitor: Acer predator x34

Strange fact is when I boot in verbose mode (with clover), the hdmi output works. What could it be?
I tried all possibile fixes: VoodooHDA, AppleACL, audio_cloverHDMI, codecCommander fix
