Onboard Sound card - F36 - how to reset configuration

Ask Fedora

Hi all,

Appreciate any help you can provide.
Fedora36, KDE Plasma.
Is there an easy way to reset audio configuration to default in Fedora?

Taking a laptop away with me on holidays. On login, the onboard sound card that I have is not detected, and the graphics card audio driver configures incorrectly.

So, no sound available at the moment. System does not detect the onboard sound card.

Normally, I use a laptop as a primary monitor with 2 monitors either side. One through HDMI, one through mini-DP. This gives audio output through the HDMI port, or the onboard card (the miniDP is not supported.) As I am away, I am using a laptop only.

However, following this hint:
https://discussion.fedoraproject.org/t/onboard-sound-not-detected-on-gigabyte-b450/26541/4

I created a new admin user.
The onboard sound card works perfectly for the new user.

I went to install pulseaudio and a lot of conflict warnings were flagged. I stopped there.
Removed and reinstalled pipewire.
Same result.
Downgraded alsa* successfully

As I store documents on a separate drive, it’s an easy matter to delete and reinstall an account to fix this, but then I have to do a bit of configuring.

Is there an easy way to reset audio configuration to default in Fedora?

With thanks,

A

I would start with removing ~/.local/state/wireplumber

pipewire’s configuration files for the user would be in ~/.config/pipewire

This told you it is not a system problem but a config problem for the normal user.
In fact you probably could have used the sound settings panel and selected the proper source for your regular user without doing any software changes.

Pipewire and Wireplumber work well for most, and if it worked for you with the external monitors but not for the laptop speaker then it was simply a config issue in needing to select the proper sink for audio output.

Audio config is a user level config.

If you remove the directory ~/.config/pipewire then restart the computer and restart an audio app it should reconfigure pipewire to the default config for your user.

This is, of course, assuming that your installation of pulseaudio did not mess other things up.

The way to enable or disable pulseaudio and pipewire-pulseaudio is normally to swap the packages with dnf. sudo dnf swap pipewire-pulseaudio pulseaudio --allowerasing to remove pipewire-pulseaudio and install pulseaudio. Simply reverse the package names to reinstall pipewire-pulseaudio.

Many thanks Jeff and Joe,

Jeff - the settings panel gave no option to select another card. It was well and properly broken.

Removing the config directories should work. I just didn’t know where they were.
Didn’t install pulseaudio - it stopped at the warnings. But in case, the command makes sense. Thanks.

I’m away from the machine for the next couple of days now.
I’ll give it a go and report back 3 Jan.

Worst case - I intentionally run the OS on a separate directory to the data. I’ll just reinstall.

HI all,
Ended up doing a brute force repair - fixed when I completely reformatted and reinstalled Fedora36 back to factory settings.

Had caused myself a login issue on both accounts, so there was one easy option, reinstall back to initial setting.

As I said, I store data on a completely separate drive, so a reload causes 30 minutes reconfiguration work, such as setting up mail clients again, reconfiguring grub on a dual boot machiine, etc… No (meaningful) data lost in the process

Regards,

A
