Problem With Hardware Detection and Sound Driver

Hi guys! I’m a relatively newer user on Manjaro (and Linux too) , i always used simpler distribution like Ubuntu. I decided then to install Manjaro (Gnome) on my external drive. I followed a tutorial for partition and i think it is okay. Problem is all drivers are correctly installed and detected, also for my nvidia graphic card(which is strange because it never worked at installation hahah) except for the sound card and i have no really idea how to find them and install, or even how linux manage his audio system. Can someone please help me?

If it is needed my pc is a HP Pavillion 16 a0021nl

If can help also on my live version on usb sound card is not working!
