If your sound settings shows Dummy output instead of displaying the sound device in Fedora, then your install might missing a certain sound card drivers.

There are times when the sound card works in the first boot or in the live session, but does not work after the installation.

There are many reason to come across this issue, one of it is to have a sound card from an unusual manufacturer.

I had this issue ever time I work up my laptop from sleep, the short term fix for this issue was to reboot the system.

In order to fix this issue completely we need to install alsa-firmware, this package offers extra drivers that don’t ship by default in Fedora.

We can do this by entering this command in the Terminal.

sudo dnf install alsa-firmware

After installing this, you need to restart your device and this issue should go away.

  1. Your post helped me to fix the dummy output issue. Thanks a lot. I used to reboot the device and If I was lucky I get the sound otherwise I ended up with playback issue with dummy output config on sound setting. I tried to fix this issue with pavucontrol and alsamixer but once it switched to dummy output, there were no way to return back.

  2. I had the impression that it fixed my problem but still I was getting same issue again and again. Later I went to recompile the linux mainline kernel 5.15.0-rc6 and it got fixed. Sometime it’s not always packages and wrapper tool to configure, after all sound card is configured with kernel module right šŸ™‚
