[Solved] Audio Volume: No output or input devices found

This is a new arch installation on a ASUS laptop. After installing KDE I found out that it cannot produce any sounds. The Audio volume bottom shows that there's no output or input devices found.
The /etc/asound.conf file isn't exists and I can't figure out how to write it after reading https://wiki.archlinux.org/index.php/Ad … chitecture

Here is some information that might be helpful:

$ uname -a

Re: [Solved] Audio Volume: No output or input devices found

There's only a hdmi card detected which is unlikely to be what you want, post

dmesg | grep -E 'snd|sof'

in [ code ] [ /code ] tags without spaces (... and edit your first post to wrap the command outputs that way as well)

Try installing the sof-firmware and alsa-ucm-conf packages

Re: [Solved] Audio Volume: No output or input devices found

After installing these two packages, KDE thinks there's audio now, but I still couldn't hear anything, no matter using the headphone or speaker.

Another information,

 $ systemctl status alsa-state

Oh, now that this problem has been solved. I pressed F6 in alsamixer and found out that there're still some channels being muted.
