No audio volume

I installed Manjaro Ornara 21.0 with KDE Plasma on my laptop a week ago. (This is my first time using a Linux distro, so please be patient with me.)

After installation, I was initially able to play music on my laptop without issues.

However, for the past day, I have been unable to play any sound, regardless of which output device I use. Rebooting does not help either. This problem happened quite suddenly, and I am not sure of the cause.

This is the output after running sudo dmesg | egrep '(snd|sound|sof)':

Any advice would be much appreciated. Thank you.

I fixed the issue by running alsamixer and then selecting the correct sound card.
