Yesterday i shredded my fedora 30 install, since it kept dying on me due to some issue with nvidia drivers breaking when updating. I then installed fedora 31 workstation and all was well until i wanted something to listen to. Turns out fedora does not detected any input or output devices, no matter if usb or through the audio jack, I tested it with multiple devices. I did not have this issue on my fedora 30 install, so the hardware should be working (with linux).

Some online research leads me to believe that my sound card is not being detected or is missing some "modules"/drivers.

Running the following commands yields this:

> aplay -l
aplay: device_list:274: no soundcards found...

I am rocking an asrock z370 extreme4 with no external sound card, so the onboard soundcard found by lspci should be the correct one. Kernel version is 5.5.13-200.

Has this happened to anyone of you people ? This issue is really annoying me, since I can't really do home office if i cant talk to my colleagues.

Since i found no real solutions to this problem, I deleted my fedora install and reinstalled it again. Now the audio works with any problems or additional tinkering, so i guess something just went wrong with the previous install.
