Tried (not working):
sudo alsa force-reload

----------------------------------------------------------------------------------------------------------------------------------------------
Tried creating a file (not working):
sudo gedit /etc/asound.conf containing:
defaults.pcm.card 0
defaults.pcm.device 0
defaults.ctl.card 0

Currently the /etc/asound.conf is deleted to get back to known original
state.

----------------------------------------------------------------------------------------------------------------------------------------------
Tried the appending the following options in /etc/modprobe.d/alsa-base.conf
#### Tried appending these one-liners - one-by-one: none worked so far (so I 
commented them out).
#options snd-hda-intel model=vaio
#options snd-hda-intel model=sony
#options snd-hda-intel model=generic

Then from https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-
Models.txt

ALC260
======
  gpio1         Enable GPIO1
  coef          Enable EAPD via COEF table
  fujitsu       Quirk for FSC S7020
  fujitsu-jwse  Quirk for FSC S7020 with jack modes and HP mic support

tried again with:
options snd-hda-intel model=gpio1
then
options snd-hda-intel model=coef

Still no sound :)
