Thank you for reply!
IOReg shows HDMI audio is not supported on DVI-2
Why I need plug TV in dvi-port-2?
Because first and main my device is monitor.
Computer loading process is showing on dvi-port-1 and I need to see the loading process.
So I regularly switching second device between second monitor on my table (if I need to work with 2 monitors), and TV, if I want to see movies.
Can you prompt me where in IOReg you see "HDMI audio is not supported on DVI-2"?
And how to config this DVI-2 port to support HDMI-audio?
cloverHDMI installs a Nvidia HDMI audio ssdt
2nd request, attach ssdt.
I have no any SSDT in /EFI/CLOVER/ACPI/patched/ folder.
May be I installed WhateverGreen first, and after when I started cloverHDMI - he didn't install ssdt?
I deleted WhateverGreen.kext, and HDMI audio on dvi-port-1 continue to work without WhateverGreen and ssdt.
How it's possible?
(Files in my previous attachment is created from config without WhateverGreen and ssdt, but with working sound on dvi-port-1)
