>>11300062there is two hdmi output on my nvidia card only 1 port showes up as audio device
on windows both hdmi can output audio
i was trying to do pci passthrough
i used igpu for linux host nvidia for guest
THE FUCKING DVI-D port on the igpu recognised az HDMI so colours are washed out and you cannot change the the rgb properties with xrandr from restricted to full because in fact it is a dvi-d port and not a HDMI port but it is recogniyed as a HDMI
also the true hdmi port on the igpu does not show up as an adio device but on windows it does
and I tried ubuntu debian gentoo and arch and got the same problem
ONLY HDMI PORT 2 ON THE NVIDIA CARD IS RECOGNISED AS AUDIO OUTPUT DEVICE
