No sound / sound card not detected / dummy output


Hello guys,
this is my first post, and honestly I'm quite desperate, because ususally I can find the solution to my problems searching the forum, but not this time.
I can not tell when or how it happened, but my machine doesn't play a sound anymore. I've tried to re-install alsa, but it didn't solve my problem. I know the problem is not hardware related because before I began to re-install alsa I could see the device with "aplay -l". But after my attempts I lost the device, and now "aplay -l" just returns "No soundcards found".

Here's the output of alsa-info.sh:

Can anyone take a look and give me some guindance? I'm not a newbie, and this is really the first time I'm kinda lost because I can not relate the loss of sound with any event, so I'm really shooting in the dark.

Thanks in advance to anyone that can give me a helping hand.

It looks like snd-hda-intel module is not loaded (from your lsmod output)
Try "modprobe snd-hda-intel"
