Soundcard not detected on fresh arch install

Hello,

I just installed arch and pulseaudio is showing dummy output and I get no audio.

Tried following several things I saw while googling around but none seem to have resolved the issue.

Some data that may help.

lspci -nnk | grep -A2 Audio

Re: Soundcard not detected on fresh arch install

dmesg | grep -E 'snd|soc'

might need https://wiki.archlinux.org/index.php/Ad … A_Firmware

If installing the firmware files and rebooting is insufficient try a /etc/modprobe.d/dsp.conf

options snd_intel_dspcfg dsp_driver=1

and reboot. But this should generally only be used if it doesn't work with sof-firmware

Re: Soundcard not detected on fresh arch install

Tried installing the firmware files on the link you gave then reboot and it still wasn't working.

Adding the /etc/modprobe.d/dsp.conf somehow fixed the audio but it turns out the mic isn't working. Tried both with a headphone mic and the laptop built-in mic and both don't work.

Running dmesg | grep -E 'snd|soc' after adding the modeprobe returns the results below.
