alsa-info data shows a deprecated modprobe option has been added to system
!!Modprobe options (Sound related)
snd_hda_intel: dmic_detect=0
!!ALSA/HDA dmesg
[ 4.462160] snd_hda_intel 0000:00:1f.3: dmic_detect option is deprecated, pass snd-intel-dspcfg.dsp_driver=1 option instead
I suggest you remove modprobe option snd_hda_intel dmic_detect=0 rather than replacing it with new option to force use of snd_hda_intel driver
A moderator has recently advised that kernel v5.15 does not have good support for Alder Lake systems
I suggest you install kernel v6.0, that should be patched to support this audio codec using sof-soundwire driver
sudo mhwd-kernel --install linux60
(Or use Manjaro Settings Manager > Kernel)
Later kernel + sof-soundwire driver should allow ALSA to detect analog outputs (ALC1319D amplifiers for speakers + headset jack) and internal digital microphone array
