System data shows the Sound Open Firmware drivers to support the internal digital microphone array (dmic) are probably installed, but only in use as alternate drivers
Device-1: Intel Comet Lake PCH cAVS vendor: Lenovo driver: snd_hda_intel
v: kernel alternate: snd_soc_skl,snd_sof_pci bus-ID: 00:1f.3
chip-ID: 8086:06c8 class-ID: 0403
I suggest you check package sof-firmware is installed to make sure all the required drivers are available for ALSA
pamac info sof-firmware
The modprobe option mentioned in OP will only work to disable the dmic for kernel v5.4 and earlier
No output of speaker (heaphone and handset working properly)
this option has now been deprecated and does not work with kernel v5.8
If you want to continue using system with the internal dmic disabled
replacing the old modprobe option with `options snd-intel-dspcfg dsp_driver=1’
should get system working as before
Problem with headphones audio
The new modprobe optionoptions snd-intel-dspcfg dsp_driver=1might not be needed if the internal microphone array is supported by Sound Open Firmware drivers
It might be possible to change the modprobe option to force use of snd_sof_pci instead of snd_hda_intel
options snd-intel-dspcfg dsp_driver=3
If that option does not support the dmic for this system you may need to contact sofproject to consider if a driver patch is needed – Issues · thesofproject/sof · GitHub
I do not see any previous issues reported for a ‘Lenovo Legion’ system
