=========
case1:
motherboard ---> hdmi wire ---> monitor
using intel graphic card（Intel UHD 770 built-in cpu 13700k), the monitor has no sound ouput, and the 3.5mm port on machine outputs sound normally. I want to make sound output normally from monitor in this case.

case2:
nvidia gpu card ---> hdmi wire ---> monitor
When conneting the HDMI to the nvidia graphic card, everything normal, sound OK.

note:
when changing to the windows system, case1 and case2 both output sound normally from monitor.

My changes:
============
1)
/etc/modprobe.d/alsa-base.conf
add a line:
options snd-hda-intel model=generic
2)
/etc/default/grub
chang
GRUB_CMDLINE_LINUX=""
to
GRUB_CMDLINE_LINUX="quiet i915.force_probe=a780"

note:
if no change 1), "HDMI/DisplayPort-Built-in Audio" does not show in Setting--Sound-Output-Output Divices , and only show "Digital Output(S/PDIF)-USB Audio", and command "aplay -l" does not show card 0.

if no change 2), command" >>dmesg | grep snd " output:
