The modprobe option in OP was a good workaround for disabling the digital microphone array in Intel laptops
but it is no longer viable for kernels v5.7.x and above
user on old forum (with kernel v5.7.0-3 posted) this message from system
https://archived.forum.manjaro.org/t/bad-audio-quality-from-earphones/153418
!!ALSA/HDA dmesg
[ 2.126856] snd_hda_intel 0000:00:1f.3: dmic_detect option is deprecated, pass snd-intel-dspcfg.dsp_driver=1 option instead
suggest users check for a similar message
sudo dmesg | grep snd
and replace options snd-hda-intel dmic_detect=0 with options snd-intel-dspcfg.dsp_driver=1
