Only Dummy Output available in laptop

Hello, I recently switched to linux from windows but haven’t managed to get sound working. I have experience with Deb distros but this is my first arch based distro.
My current kernel is 5.10 (I tried a few different ones to see if it would fix the issue) and I’ve done all the fixes I found online, but with no success. Sometimes the Dummy Output disappears but I still only find HDMI output (I don’t have a device connected to HDMI) and still no sound.
Here are some outputs that might be useful:

[me@me-voomexcellence ~]$ aplay -l

Thanks a lot in advance!

Oh, and I forgot my inxi output.

Did you try reinstalling sof-firmware?

Take a look at https://www.reddit.com/r/archlinux/comments/nkscuf/sound_card_not_being_detected/

sof-firmware has been orphaned:

https://wiki.archlinux.org/title/Advanced_Linux_Sound_Architecture

Package sof-firmware was previously marked as a dependency in 2 metapackages – manjaro-pulse and manjaro-pipewire

But sof-firmware is not a required dependency of either PulseAudio or PipeWire

Sound Open Firmware is required for Intel laptops to support digital array microphones in ALSA
Users on Intel laptops should change this package in pamac-manager by clicking on Mark as explicitly installed

Intel desktop systems might need Sound Open Firmware in the future when it supports use of onboard audio processing. But I do not know of any plans to add DSP support, so it is not likely to be happening soon

AMD Audio Co-Processor support for digital microphones is included in the kernel, so AMD systems do not require this package
