No sound card detected

I just installed Manjaro KDE.
The last time I installed it, everything functionned perfectly, but this time, on the same PC, there isn’t any sound card detected.
Can somebody help me please?
it is a realtek sound card I think…


We can’t go by guessing. Please see here How to provide good information
and Sound not working after upgrade - #39 by nikgnomic to know how to find the correct info about that card.

is pipewire up to date?
