[Solved] ALC256 (Intel Raptor Lake) not working properly

After installing Arch Linux on my ASUS laptop and configuring sway/wayland, I noticed that the audio wasn't working and no card was detected.
As stated in ALSA's wiki page in firmware section, I found the sof not found error in the log so I installed sof-firmware. After unmuting in alsamixer, speakers are working only from one source at a time (mixing is not working, I already tried installing alsa-plugins and creating .asoundrc) and internal mic is detected but doesn't capture any audio other than some noise only present when I max out the volume of PGA2.0 channel in alsamixer.

Installing pulseaudio actually solved the output issue regarding mixing.
For the microphone issue, I solved it by setting the digital microphone as my default one
