Can't Disable HDMI Sound Power Saving

[#&thj^%]

I seem to have over estimated here:
Your original grub file looked like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

The change should look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel power_save=0"

Nothing else there>>> but what I show in the above^^^^
update grub and reboot

That's what I meant by your grub looking different. My said quiet splash. Well, I pasted your first version and rebooted and it didn't break anything. It just booted for 30 seconds.

I changed the grub again. Updated grub in terminal and rebooted. No improvement. I checked again and snd_hda_intel power saving still turned ( itself? ) to "1".

Have you made changes to any sound related settings prior to this thread?
Some realtek cards have rules of their own, not good for a user.
Lets check what you are working with:

inxi -A

NOTE: this is a sample of mine only.

Audio:
  Device-1: NVIDIA driver: snd_hda_intel
  Device-2: AMD ACP/ACP3X/ACP6x Audio Coprocessor driver: N/A
  Device-3: AMD Family 17h/19h HD Audio driver: snd_hda_intel
  Device-4: DisplayLink UOEOS Laptop Dock type: USB
    driver: cdc_ncm,snd-usb-audio
  Sound API: ALSA v: k6.1.4-1-default running: yes
  Sound Server-1: PipeWire v: 0.3.64 running: yes

I only changed and_hda_intel power saving to 0 manually. And attempted to make a service file which would loop a "silent" sound to keep the sound card from sleeping ( didn't work, apparently ).

Audio:

I run in a different circle, bleeds over to user forums..
OK Plainly worded now.
I still need to know, Have you made changes to any sound related settings prior to this thread?

It's only a guess on my part, but that could be the differences between yours and my findings.

[nobody96]

The service file was only an autostart for a sound looping. Nothing more to it. The .service file isn't even there anymore.

sys/module/snd_hda_intel/parameters/power_save changes value to "1" after reboot, and power_save_controller changes value to "Y" .

I don't know if that's important, but I do have a realtek sound card. Shouldn't it appear on

inxi -A

?

There is a

snd_hda_codec_realtek

folder in

/sys/module/

Under

/sys/module/snd_hda_codec_realtek/drivers/hdaudio:snd_hda_codec_realtek/hdaudioC1D0

there is a "chip_name" file, it says "ALC1220"

Bingo there it is....
It should show as realtek in a perfect world, some vendors just do things different.
I'm not sure how to advise you now.
Don't kill the messenger:

Reltek HD-audio drivers have the automatic power-saving mode. This feature is enabled via Kconfig CONFIG_SND_AC97_POWER_SAVE and CONFIG_SND_HDA_POWER_SAVE options, respectively.

With the automatic power-saving, the driver turns off the codec power appropriately when no operation is required. When no applications use the device and/or no analog loopback is set, the power disablement is done fully or partially. It’ll save a certain power consumption, thus good for laptops (even for desktops).

Well, this sucks.
I wonder who was the person that thought that was a good idea.
Thanks for trying.

Perhaps, someone here can tell me how to make a working, looping dummy silent sound process that autoruns on boot and keeps the sound card from going to sleep. The one I found somewhere else didn't work for some reason. I wanted to paste what was in it exactly but I can't to find the source.
