Nvidia Card show as disconnected HDMI / DisplayPort (disconnected)

Hi guys, how are you?
I'm facing a problem with my hybrid laptop, I can't see my NVIDIA sound card, I believe it was after the system update, I don't know yet, a while ago I was having a problem with audio coming out of the dummy output, but I managed to solve it editing /etc/modprobe.d/alsa-base.conf and put options snd_hda_intel enable=1.0, and before they showed my 2 sound cards through the command cat /proc/asound/cards.
But now, I can't see my NVIDIA sound card, I'm trying to listen to the sound through the HDMI output, with my laptop connected to a TV, before it worked perfectly, I never had any problems with it.

I can't see it either when I execute the alsamixer and try to select my NVIDIA card.

There is the output of lspci | grep Audio:
00:1f.3 Audio device: Intel Corporation Comet Lake PCH cAVS
01:00.1 Audio device: NVIDIA Corporation Device 10fa (rev a1)


There is the output of cat /proc/asound/cards:
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xc4510000 irq 175


There is the output of aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC274 Analog [ALC274 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1
  Subdevice #0: subdevice #0

There is the output of cat /proc/asound/modules:
0 snd_hda_intel

Any help would be greatly appreciated.
