You don't need to worry about the Nvidia audio being named 'Unknown' in DPCIManager. It is a cosmetic issue.
You need to look in System Information and the Audio report to see what is showing up.
Here is a screenshot showing my Audio tab/report as an example of what you might see.
Your main audio for your system is the Realtek ALC1150, which is accessed via the ports on the rear I/O plate on your motherboard.
WhateverGreen.kext and Lilu.kext should make your HDMI audio work, if that is what you are using. However you will have no volume controls for the HDMI audio within macOS. Not unless you install a third-party Audio app. All HDMI audio is controlled on the display/TV you are using.
Hi all;I come to you because I don't know what to do anymore ...the friend I built my first Hackintosh with is dead and I can't seem to finalize my updated setup from Yosemite to Mojave.So I allow myself to call you for help, I have made a file with the specifics of my configuration, the copy of the EFI and the latest kernel panic report that I had with the analyzes via RunMe.You should know that my hackintosh has not worked well since the last security updates for Mojave 10.14.6.I have fairly regular system crashes and I happen to have them during the reboot of the machine.Small clarification, the machine has become very slow and the hdd activity led remains on permanentlyThanks in advance for your help
