according to 
https://wiki.ubuntuusers.de/Soundkarten_konfigurieren/HDA/

the snd-hda-intel driver knows an option "model=vaio" ...
try using:

options snd-hda-intel model=vaio

in your /etc/modprobe.d/ adjustments instead of model=generic ... 

if you look at
https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html

there seem to be a few more vaio and sony related models you could try
...
