I just freshly installed Manjaro and I dont have any sound

I just freshly installed Manjaro and I dont have any sound. I am new to arch based linux please help.

I lose sound when I run the 5.13 kernel. When I use the 5.10 kernel, the sound is back. DISCLAIMER I run KDE Plasma.

EDIT Welcome to the forum. I hope you will enjoy Manjaro as much as me.

EDIT 2 Check this out:

Did you check alsamixer?

I have the same issue. I have raised this in another thread.
