I installed back Nvidia drivers (by selecting Additional Drivers -> "Using NVIDIA driver metapackage from nvidia-driver-440") when in kernel 5.4. First time gave me some errors. Then it did the switch.

Now 3x in a row the laptop booted with 5.8 (WITHOUT nouveau.modeset=0).

~$ sudo lshw -C display

       description: VGA compatible controller
       product: TU104BM [GeForce RTX 2080 Mobile]

Looks like nvidia proprietary drivers are not loaded and Nouveau ones are used.

Now the behavior is:
- with "options snd-hda-intel dmic_detect=0": output device works, input device empty
- without "options snd-hda-intel dmic_detect=0": output device Dummy output, input device empty
