snd_hda_intel no codecs found! no sound

SollyBunny · 2021-09-01 07:24:36

I've just reinstalled arch and installed pulseaudio, alsa, alsautils & pulseaudio-alsa but my Audio card isn't being detected in anything but lspci

lspci
...
00:16.0 Communication controller: Intel Corporation Cannon Lake PCH HECI Controller (rev 10)

In dmesg there's errors for snd_hda_intel

snd_hda_intel 0000:00:1f.3: Unknown capability 0
snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0
snd_hda_intel 0000:00:1f.3: no codecs found!

According to this post (on the artix forumns) someone has this error with the exact same card this worked:

# /etc/modprobe.d/intel_dmic.conf
options snd_hda_intel dmic_detect=0

however that didn't affect anything for me

Reloading the device also just produced the same errors in dmesg

echo 1 > '/sys/bus/pci/devices/0000:00:1f.3/remove'
echo 1 > /sys/bus/pci/rescan

Same happens removing and readding snd_hda_intel module

Did/do you have the "sof-audio-pci" errors?
Did you install linux-firmware?
Which kernel (version) is this?

Ideally please post the complete system journal (sudo journalctl -b)

Did/do you have the "sof-audio-pci" errors?

I don't think so

Did you install linux-firmware?

yes

Which kernel (version) is this?

5.13.13-arch1-1

Ideally please post the complete system journal (sudo journalctl -b)

Also sorry I copied the wrong thing from lspci (still isn't exactly the same)

You aren't going to have sof firmware errors if you disable it via dmic_detect. Remove the modprobe file and install sof-firmware and reboot.

I do have sof-firmware installed aswell
I'll see what happens if i remove the modprobe file

edit: nothing changed
