The modprobe option hda-intel dmic_detect=0 used to be the workaround to disable the digital microphone array (DMIC) and continue using audio whilst support for the DMIC was being patched
This option was replaced for kernel v5.8 or later with options snd-intel-dspcfg dsp_driver=1
But the internal DMIC is now patched and working if the latest packages can be obtained
so the modprobe option may not be needed
The SOF driver sof-hda-dsp driver is present and recognised in PulseAudio
System will need a recent kernel > v5.8. As this is very a new laptop it may need kernel v5.9
And it also needs a later version of PulseAudio (v13.99) patched to support sof-firmware
the simplest way to get that at the moment is to change to Manjaro testing branch
@BusinessOrc please do not encourage post bumping. just saying you can not help further is enough. but you could also post my username on an audio issue to have a look at it
