I created a bootable USB and loaded ubuntu to test if the HW is fine. The sound was working there. So, the HW is fine.
Guys, please help me solve. Thanks.

Hi,
If it's working in a live Ubuntu environment, would it be possible for you to run
there and see if there are any differences?
You could store the output of those commands in text files and compare them with diff to speed things up a bit.

There are significant differences in both the outputs. Could you please have a look.
http://www.mergely.com/editor is a nice tool to compare texts online.

FWIW, a thread dealing with the same intel chipset (9dc8)
https://www.linuxquestions.org/quest...ly-4175671642/
It's not yet resolved, but likely impacted by the same underlying cause, so worth following.

Please refer to posts #8 and #9 of that thread. Try adding the kernel parameter to your grub configuration. Keep your replies here.

Oh yeah.. Adding that to the grub boot configuration helped. It also solved the suspend issue I had (suspending freezes the screen).
Thanks Ferrari. Thanks guys.
