Hello Fellow Fedora Users,
I have run into a snag with my system audio after recently upgrading my system to Kernel 5.5.15-200.fc31.x86_64. Sound only outputs as dummy, however, my built-in audio and sound card are listed with the lspci -nn command. I checked the alsa-info.txt and nothing regarding my devices shows up. I’m not sure why Fedora forgoes my audio after a simple update, any ideas?
Any assistance would be greatly appreciated.
I too recently had Dummy Output, but unsure exactly when this started, as my USB headset was working. Only when I tried to use the laptop away from my desk/dock did I notice this. I have now resolved my problem, perhaps it’s the same for you.
The first thing I did was look at journalctl filtering to today’s date and again to audio.
journalctl | grep "Apr 13" | grep audio

Here I saw that there was a failure to load the firmware etc. So did some research around that and found this post (https://bbs.archlinux.org/viewtopic.php?id=251157). Here they mention setting a kernel parameter, which solved my problem.
Note: I am on Fedora Silverblue, so these may not apply to your setup.
Append snd_hda_intel.dmic_detect=0 to my kernel parameters and rebooted.
rpm-ostree kargs --editor
Append snd_hda_intel.dmic_detect=0`
systemctl reboot
Hope this helps.
Hello and thank you for the reply,
I ran the command journalctl and here’s what I got.

I’ll take a look at the solution you provided and post my results. 
Hello again, I tried the solution you posted. Unfortunately it didn’t work, rpm-ostree doesn’t want to run the command instead it returns “error: the system was not booted via libostree”. I appended snd_hda_intel.dmic_detect=0 to grub as suggested in the forum post (https://bbs.archlinux.org/viewtopic.php?id=251157) with no luck.
Sorry for the massive delay.
rpm-ostree is a Silverblue package manager command. If you’re on vanilla workstation it will be different. I don’t know what that is though.
Try Dummy audio output after update - #2 by stemid
Thanks for these instructions. Do you know the difference between using snd_hda_intel.dmic_detect=0 and snd-intel-dspcfg dsp_driver=1?
Are these necessary too? Are they legacy drivers, or otherwise why are they in a separate package?
