Would you mind to try this method for native ALC1150 (based on toleda's method)?
1 - Get rid of everything VoodooHDA related, rebuild cache and reboot
2 - In EFI\EFI\CLOVER\config.plist add
comment Rename ALZA to HDEF
Replace* [HEX] 48444546
3 - In EFI\EFI\CLOVER\config.plist set value 1 in Devices>Audio
Audio 1.png 331.84KB
4 - Rebuild cache and reboot again (no audio In/out)
5 - Find the right location of your Graphics Card with IORegistryExplorer looking for "display0" (for me BR2A@2)
nVidia loc.png 96.94KB
6 - Download toleda's audio_hdmi_amd-nvidia-master folder from here and find the right ssdt.aml from ssdt_hdmi-nvidia folder that would match your graphics card location (in my case I had to custom toleda's SSDT-HDMI-NVIDIA-BR3A.aml).
7 - Put toleda's ssdt.aml in EFI\EFI\CLOVER\ACPI\patched folder, rebuild cache and reboot
8 - Mount EFI partition
9 - Download toleda's script from here
10 - Run toleda's script and type password, and "y" (no quotes) for yes a bunch of times, until the end of the process

11 - In EFI\EFI\CLOVER\config.plist add
Replace* [HEX] 208D
in Kernel and Kext Patches>KextToPatch
12 - Rebuild cache and reboot
You should have onboard audio and HDMI as well.
Please note that you may need to add CodecCommander.kext (attached here) to S/L/E to prevent on board Audio failure after wake from sleep (on ALC1150).
Let me know if it works.
