An alsa info link here - http://alsa-project.org/db/?f=ac274d...7cd02bec8e6de3

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

Code:

lsmod | grep snd

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.

Thanks for the reply redd9

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.

Thanks again.

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.

It's now resolved for the OP in the thread I linked to. Follow the advice given in this post and report back.

Yeah, I just noticed that same thread. Definitely check it out!

Thanks for sharing that Ferrari. I added a comment with more details there. Please check it out.

Thanks

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.

Well done. Glad to have been of guidance!
