After upgrading from Linux 5.3 to Linux v5.4.2 on Arch Linux, all of my audio stopped working. The only thing I see in Gnome 3’s Sound settings is “Dummy Output” and
aplay --list-pcm says: “No card(s) found.” and running
alsactl init says: “alsactl: init:1759: No soundcards found.”
I’ve tried many solutions already.
