Hello i discovered, that when using "amdgpu.dc=0 amdgpu.audio=0" krenel
parameters in a dvi-d to vga monitor setup i get screen flickering with full
screen video players and redshift.If i use only "amdgpu.dc=0" there is no
screen flickering but hdmi audio is enabled (which is useless in my setup)

If you are using DVI or VGA, audio is irrelevant anyway so why do you care
about the audio option?

because pulse audio always defaults to hdmi-audio first

ok i used the "pactl unload-module" option at startup to unload hdmi device,
but
it took me a while to figure it out, anyways a clean flicker-free kernel option
to disable hdmi would be preferable instead of trying to hack pulseaudio.
