[SOLVED] Sound not working after fresh Arch install

I have a fresh Arch install and cannot get the sound to work. I have browsed through the forum and could not find any solution that works for me.

Some outputs:

$ speaker-test -c 2 

speaker-test 1.2.5.1

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 1048576
Period size range from 32 to 349526
Using max buffer size 1048576
Periods = 4
was set period_size = 262144
was set buffer_size = 1048576
 0 - Front Left
 1 - Front Right
Time per period = 12.018637
 0 - Front Left
 1 - Front Right

I don't hear anything when I run the speaker-test. I did use alsamixer to unmute all the channels. I also created an alsa.conf file to load the sound card modules as advised in the ALSA Wiki:

$ cat /etc/modules-load.d/alsa.conf |
snd-hda-intel
snd-pcm-oss
snd-mixer-oss
snd-seq-oss

Any help would be greatly appreciated!

Thanks!

Re: [SOLVED] Sound not working after fresh Arch install

Your non-HDMI card is a sof card, install sof-firmware and reboot (... and remove snd-hda-intel from the modules-load.d, and probably the entire file, it's quite unlikely you'll run into anything still requiring OSS) : https://wiki.archlinux.org/title/Advanc … A_firmware

Thanks so much! That worked indeed .
