snd_hda_intel blocks/freezes suspend

[Marcin]

Since some packages upgrade(probalby couple months back; when I had LTS bionic) I'm unable to suspend my PC.

I thought installing newest LTS focal will solve this problem but it didn't - system freezes on suspend displaying plymouth last screen.

I found debug howto here : https://www.kernel.org/doc/Documentation/power/s2ram.txt

What I found according to it:

$ cat /sys/power/pm_trace_dev_match
resulted in: block and snd_hda_intel

as I was unable to force :
$ modprobe -r -f snd_hda_intel
modprobe: FATAL: Module snd_hda_intel is in use.

I did change /etc/default/grub to:
GRUB_CMDLINE_LINUX="snd_hda_intel.blacklist=1 modprobe.blacklist=snd_hda_intel"

then sudo grub-update.

After reboot suspend was finnaly working correctly
but I've NO sound now:(

Googling on the internet I found:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/commit/queue-5.0/alsa-hda-don-t-trigger-jackpoll_work-in-azx_resume.patch?id=ae96827ca4096488ee460a071834fe03022172d7

Is it possible that's the change that broke my suspend?

my board: Gigabyte GA-F2A88XM-DS2.

Can you fix this problem?

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Marcin (mwoz123)]

I workaround it thanks to this: https://bbs.archlinux.org/viewtopic.php?pid=1404929#p1404929 :

```
In "/etc/modprobe.d/intel.conf" put:

options snd_hda_intel enable=1,0
This is how you disable or enable specific audio hardware when they share the same driver. If the wrong one gets disabled then replace "1,0" with "0,1"

```

I disabled Nvidia snd_hda_intel and kept my ALC887 from motherboard on,
and now suspend works and also I've sound transmitting from my motherboard to speakers.

Nvidia HDMI output provides video, but probably not audio :/
It's an issue but right now not too big for me

[Kai-Heng Feng (kaihengfeng)]

Is it possible to find the last working kernel?

[Marcin (mwoz123)]

No. I won't be able to find it as I already upgraded to focal.
I'm not 100% sure if it was a kernel updated or other software anyway on 20.04 issue still exists.

My workaround (disable nvida hdmi audio) is 2 posts above: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1882945/comments/3
