Realtek ALC1220 appear as generic and has no controls.

Hi,
It's been a long time since I've posted here. This time it won't be a cryptic and deeply specific GPU thing.
In the past on all my machines my experience with sound on gentoo was very painless and quite amazing: enable snd_hda, enable the right card, install alsa and I didn't even need to play with asound.conf it just worked out of the box.
But this time, I have a quite simple setup which I know is supported (https://forums.gentoo.org/viewtopic-t-1099046-start-0.html)
My machine has two sound devices:
A GPU with HDMI output (which I do *not* want).
A motherboard embeded which lspci -k report as:

What happens if you enable this ? ->
https://wiki.gentoo.org/wiki/User:Pietinger/Experimental/Manual_Configuring_Current_Kernel#Serial_Bus_Multi_Instantiate

If this does not help we would need: Boot with our GentooLIVE-CD and do a "lsmod" and a "lspci -nnk". Maybe also a "dmesg" would be helpful. And last but not least your current (complete) kernel .config.

I tried to enable the "Serial bus multi instantiate pseudo device driver" but it didn't help unfortunately.
After booting on a live usb the lspci -nnk for the ALC1220 looks like:

I can see from your kernel .config that you already have a lot of experience with configuring a kernel. You have already done what I always recommend: Boot with a LiveCD and check with “lsmod” which modules have been loaded. That will certainly help here.

It may already help if you enable CONFIG_SND_HDA_CODEC_HDMI ... but I suspect that we need even more. Have a look at this module list:

P.S.: I forgot something ...

Please do a "cpuid | grep x2APIC". If you get "x2APIC: extended xAPIC support = true" THEN you MUST do:
1. enable CONFIG_IRQ_REMAP
2. enable CONFIG_X86_X2APIC
(you must first enable 1, because 2 depends on 1)

P.P.S.:

I have only checked Sound, USB and system ... now I have accidentally seen this (in case you have problems with the graphics):

[newin]

That's some very nice catch you got ! I didn't know about CONFIG_IRQ_REMAP and x2APIC thanks !
I also saw those a while ago then forgot about them, surprisingly I don't have any issue with my graphics. Which is very surprising seeing the type of error and what I do with my GPU (I'm a graphics programmer). I'll probably fix that when I/we are done with that sound issue.

I also came across a snd_hda_intel 0000:18:00.6: no codecs found! that I missed in my dmesg before which would point into the CONFIG_SND_HDA_CODEC_HDMI you mentioned. I tried, didn't fix the issue, so I tried to go ballistic and just enable all codec. Which still didn't help.
Then I got the very nice idea to actually try my audio on the livecd, here is what I found:
It looks like alsa is reporting one sound device per screen despite being plugged on the same GPU. That's one mystery down.
Now alsamixer on the live do have the right controls but (and that's the interesting part) I the sound doesn't work. It does no problem on HDMI but it doesn't on the jack.
That lead me to check why it wouldn't work on the live... and a dmesg later I came across that line same line:

Hmmm ... if it works with Ubuntu it has to work with Gentoo also ...

The reason I asked for "lspci -nnk" is that we can see there the Manufactor ID ... and sometimes you will find interesting pages when you google for "1022:15e3" (or "linux 1022:15e3" or gentoo ...) ... Oh no ... we have two machines with that sound in our Wiki:

https://wiki.gentoo.org/wiki/ROG_Zephyrus_G14_(2022)_GA402#Kernel
https://wiki.gentoo.org/wiki/HP_Elitebook_845_G10

... and I found also: https://cateee.net/lkddb/web-lkddb/SND_SOC_AMD_ACP3x.html

I just realised what I said earlier was looking a bit confused. I couldn't get sound on the ubuntu live I have of that sound card. Both my gentoo and my ubuntu live are giving me the same "no codecs found!" error. I couldn't get sound with that card on both.
Also, the two example you linked are laptop and the kernel SND_SOC_AMD_ACP* are described as SOC, that also include the link I posted at the very beginning.
That lead me to believe the card doesn't work outside of an SOC configuration.
The only instance of that card mentioned on linux is this HW probe: https://linux-hardware.org/?probe=f57c7238f4 (which is exactly my motherboard surprisingly). It only mention a "detected" not "works".
In doubt I tried the SOC_AMD_ACP in version 3x like you linked or with the v6 that is mentioned in the ROG setup but none of them worked.
At this point, I kind of lost hope to see it getting it to work at all. This lead me to change my setup and use my HDMI output instead. I could get it working in a couple minutes. I just have one strange bug where the meters in alsamixer I've configured in my /etc/asound.conf don't appear until I start speaker-test for some reason, but I guess that's another story.

If you don't have any ideas anymore I think I will close this on a Jean Luc Picard quote “It is possible to commit no mistakes and still lose.”

[pietinger]

If a hardware does not work under Ubuntu it usually means that:

a) it is too new and no kernel drivers exist for it yet (because Ubuntu patches the kernel extensively), or
b) an old Ubuntu version is still being used.

So if you have used the latest Ubuntu ... I see black ...and we probably have to wait for new kernel versions.


P.S.: I am (also) a big fan of Jean Luc Picard.

Just wanted to come in and say that this thread may not have solved OP's issue, but it solved mine! Who would've thunk onboard audio might be wired as a USB device?! Why isn't CONFIG_IRQ_REMAP required for CONFIG_X86_X2APIC to be enabled? Regardless, I now have sound, so thank you!
