Red Hat Bugzilla – Bug 1308971
Dummy audio driver (no sound) after upgrade from F21 to F22, not fixed in F23
Last modified: 2016-02-16 17:22:17 EST
Description of problem:
ASRock 960GC-GS FX desktop motherboard
Realtek ALC662 sound chipset that uses HDA audio
Version-Release number of selected component (if applicable):
4.3.5-300.fc23.x86_64+debug #1 SMP
Steps to Reproduce:
1. Have Fedora 21
2. Update to Fedora 22
Actual results: Sound doesn't work, all it shows is a 'dummy audio output' and no audio inputs.
Expected results: The sound should work and there should be at least two available audio drivers: the motherboard's and the graphics cards's HDMI output.
I upgraded from Fedora 21 to Fedora 22 and the sound went away. I then upgraded from F22 to F23 and I still have the same issue.
Is there a way to reset or reinstall the audio drivers?
A liveDVD Fedora 23 does have sound, it's just the upgrade killed it somehow.

I also deleted the pulseaudio configuration files in ~/.config/pulse
The output of aplay -l:
aplay: device_list:268: no soundcards found...
The output of aplay -L:
Discard all samples (playback) or generate zero samples (capture)
PulseAudio Sound Server
Default ALSA Output (currently PulseAudio Sound Server)
Any help is greatly appreciated!
I should add that the sound still worked if I switched to the old F21 kernel, but no kernel from F22 and F23.
Unfortunately, I upgraded my system and now my old F21 kernel is gone.
A related bug may be this one: https://bugzilla.redhat.com/show_bug.cgi?id=1255070
This was fixed by compiling a separate kernel with the config:
I don't understand why the Fedora-delivered kernel does not have this enabled.
This is not a real fix, just a workaround, since asking people to compile their own kernel is not a solution generally applicable.
