alsa-project/alsa-lib issue #475 was opened from aaaaadrien:

Hello,

Since an update on Fedora Linux 42, Audio card not detected, GNOME only shows "Dummy Output". No sound over speakers or HDMI. I downgraded the package alsa-lib (from alsa-lib-0:1.2.14-3.fc42.x86_64 to alsa-lib-0:1.2.13-4.fc42.x86_64) and now i have sound again. Tested with OpenSuse Tumbleweed Live ISO GNOME, with libasound2-1.2.14, i reproduce the issue.

So i think it's not a distro issue but an ALSA Issue. That's why i open a bug here.

Laptop model : Dell Latitude 3510 Audio Device : Intel Comet Lake PCH-LP cAVS driver: sof-audio-pci-intel-cnl API: ALSA version: k6.16.4-200.fc42.x86_64 status: kernel-api

Reproducible: Always

Steps to Reproduce: 1. Update alsa-lib to 1.2.14-3.fc42.x86_64 2. Reboot 3. See you only have dummy output

Actual Results: No sound

Expected Results: Sound always here !
