ALSA Audio not working

I installed Arch on a new laptop and cannot get the audio to work.

The internal speakers or the headphone jack does not work, but external audio DOES work.
Audio on an external monitor works and I also tested connecting usb-c headphone, which work as well.
So it seems only the internal devices have some issues.

I reinstalled Pulseaudio multiple times and also tried Pipewire, which both had the same results.
I think I narrowed the issue down to ALSA, where I can execute "aplay piano2.wav" with the external devices, but there is no output for the internal ones.

pavucontrol shows the device, recognizes when a headphone is plugged in and shows the audio levels.
I am very certain the devices are unmuted, I followed guides to save the amixer config and disabled auto-mute.
There no real error messages in dmesg or anything else I know of.

I notice that when I changed the volume of the microphone input or run "cat '/proc/asound/card0/codec#0'", there is a very very slight noise playing in the headphones.

Any help is appreciated!

Device information:
aplay -l shows:
    card 0: PCH [HDA Intel PCH], device 0: ALC1220 Analog [ALC1220 Analog]
  and
    card 0: PCH [HDA Intel PCH], device 1: ALC1220 Digital [ALC1220 Digital]

lspci shows: 00:1f.3 Audio device: Intel Corporation Comet Lake PCH cAVS

Edit:
Might be useful to mention, the speakers and headphone jack work completely fine on windows.

Re: ALSA Audio not working

Output of "amixer"?

Re: ALSA Audio not working

That's PA, since the problem seems to be w/ alsa below PA, stop PA and run amixer again (the output should be muuuch longer)

Re: ALSA Audio not working

Is the sof-firmware package installed? Which kernel module is the internal card using?

Are you infected with Wetiko?

Re: ALSA Audio not working

You can also do amixer -c0 to access the underlying card directly. This doesn't look like sof firmware issues to me as I wouldn't expect the card to be visible at all.

What's your

amixer -c0
pacmd list-cards
pacmd list-sinks
pacmd list-sink-inputs
sudo dmesg | grep -E 'snd|sof'

Re: ALSA Audio not working

Thanks for your responses.

Yes I have sof-firmware installed. I think the snd_hda_intel module gets loaded.

Re: ALSA Audio not working

Simple mixer control 'Headphone',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 87
  Mono:
  Front Left: Playback 0 [0%] [-65.25dB] [off]
  Front Right: Playback 0 [0%] [-65.25dB] [off]

So at least the HP are on mute - no idea how significant that is for "the internal speakers" but assuming this is a notebook, they might be the same logical device (and swapped by BIOS on the plug detection)

Re: ALSA Audio not working

I just unmuted it with "alsamixer" and see no difference unfortunately

Re: ALSA Audio not working

To be sure: your OP claims that "I narrowed the issue down to ALSA, where I can execute "aplay piano2.wav" with the external devices, but there is no output for the internal ones."
Is that because you shutdown pulseaudio and tested w/ only alsa or is it because you used "aplay" to play a tune?

In case of the latter, please stop pulseaudio and see whether you get sound.
I'm not sure what to make out of

analog-output-speaker: Speakers (priority 10000, latency offset 0 usec, available: unknown)
…
analog-output-headphones: Headphones (priority 9900, latency offset 0 usec, available: no)

but in 99/100 cases the answer to "my linux has no sound" is "because of pulseaudio", so we should ensure to have really narrowed down the issue.

Re: ALSA Audio not working

I completely uninstalled pulseaudio, pipewire and all related packages I could find. After restarting I tried playing a sound with ALSA without even starting the Xserver to have as little interference as possible.
Since then I reinstalled PA, since I did not think this would change anything anyway, that's why it appears here.

For the status you mentioned, if I plug in the headphones it shows available: yes for the headphones and available: no for the speakers.
But the headphone connected via aux do not work either.

Re: ALSA Audio not working

There's the muted "beep", not sure wthether that would refer to the internal speakers.
Also make sure that windows isn't hibernating (3rd link below)
