Modprobe option snd_hda_intel.dmic_detect=0 was used on earlier Linux kernels to disable the internal digital microphone array (dmic) and use legacy audio driver snd_hda_intel
But this option was deprecated and replaced last year from kernel v5.7
Remove HDMI/DP 1 DP 2 etc from System Sound Menu?
dmic_detect option is deprecated, pass snd-intel-dspcfg.dsp_driver=1 option instead
But kernel v5.14 has new driver snd_sof_pci_intel_cnl that should support the internal dmic without causing problems for the other analog and digital inputs and outputs
Manjaro dual boot no sound
But disabling the dmic might no longer be necessary
Kernel v5.14 has new Sound Open Firmware drivers that should now support the internal dmic
So I would suggest you first remove the deprecated option from GRUB configuration and check if all audio, including the dmic, is working OK
If that is not working for you, use this command to add the new modprobe option to disable the dmic and revert to legacy driver snd_hda_intel
echo 'options snd-intel-dspcfg dsp_driver=1' | sudo tee -a /etc/modprobe.d/alsa-legacy.conf
System data is also showing 2 incompatible sound servers running – PulseAudio and Pipewire
See this post for how to disable PipeWire or replace PulseAudio
@kearney - the dmic has to work on the proprietary OS to support digital assistant surveillance software (C***tana)
