1. Please describe the problem: Dummy output in the sound settings of Fedora 2. What is the Version-Release number of the kernel: 5.3.12-300.fc31.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : This happened on an upgrade from Kernel 5.3.10 to kernel 5.3.12 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Update and restart 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag.
On what hardware are you seeing this? There was a bug in the recent alsa-lib-1.2.1 update which causes this issue on Bay- and Cherry-Trail based hardware. If you are hitting that issue then this should be fixed by the alsa-lib 1.2.1.1 update which is currently in the stable updates repository now: https://bodhi.fedoraproject.org/updates/FEDORA-2019-d70ab6e7a2 So a simple "sudo dnf update 'alsa*'" followed by a "killall pulseaudio" might fix this.
