I did `echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef ` and I attached the output but you are probably interested in this:
Node 0x20 [Vendor Defined Widget] wcaps 0xf00040: Mono ..... 447c447

Coeff 0x1f: 0x0000

< Coeff 0x30: 0x00b1
Coeff 0x30: 0x0090
And after I reset the two processing caps, the sound is back again.

I'm not sure that this are the correct parameters of hda-verb (because I lack the knowledge of alsa development) but based on the result it seems to be correct
Yes, the command sequences are correct (sorry I didn't write it in details). Mostly only some of these bits are mandatory, but only Realtek knows this secret...
