No Audio Over Hdmi Nvidia + Intel Laptop

No need for any of that, I found out the problem was alsa not saving the levels and the setting to use my headphones nor my speakers. I made it work by looking into the arch wiki and some forum answers about it and they recommended to uses alsactl storeand alsactl restore after boot, but alsamixer was not saving the settings on the default location so I started saving the config on a file inside ~/.config/ with alsactl --file [location] store and sleep 5 && alsactl --file [location] restore on a .desktop init file for kde.
About the HDMI output audio device, the change didn't help me with it, actually it didn't change anything about the devices alsa showed but showed me a "easier" way of controlling my audio and microphone (now I'm looking for noise canceling on the mic).

Although your suggestion of changing to pipewire was not at all useless, I found my answer elsewhere.

What I found is that mhwd actually disables the gpu's audio source on the rules for whatever reason. I found it while looking for the same problem with ubuntu users on this :sound - NVidia 460 update disables HDMI audio output - Ask Ubuntu that also linked to this: No HDMI Audio on Nvidia 1660 Super (Driver 460) & Ubuntu 20.10 - #5 by duffleda - Linux - NVIDIA Developer Forums where I found what I was going to have to look for, but instead of it being under /lib/udev/rule.d it was on /etc/udev/rules.d/90-mhwd-prime-powermanagement.rules where the second line was uncommented

# Remove NVIDIA Audio devices, if present
#ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x040300", ATTR{remove}="1"

when I commented and restarted the laptop the hdmi output worked and shows on the inxi!
