From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Speakers -> Worked via Line OUT for months
Take PC apart and change PSU, assemble PC back.
Speakers - Line OUT detected but can't test Left/Right audio channels, options missing. No AUDIO from speakers unless I select them as default in Pavucontrol or manually assign outputs via Helvum.
Fedora 43 GNOME
How do I get my GNOME audio settings to work again?
This is so random and funny at the same time... yet frustrating because it makes no god damn sense :D
I have a stupid question: Are you sure you're not confusing "line out" and "headphone out"? They're different, and pretty much every desktop supports both these days. But standard PC speakers usually connect to the "headphone" socket.
Save yourself the time and boot into a live distro with gnome, like the latest Ubuntu or something. Sanity test. Make sure it works there before trying to fix your own install.
I will give it a try tomorrow.
Hmmm. Random guess: does your machine have another audio output, possibly via HDMI, that you're not using? This could be ALSA selecting the wrong device as a default, which would then propagate up through the stack.
I do via USB. I tend to switch between speakers and headphones. But other audio outputs work via the audio settings when I select them
I'm currently learning about it, so I can't offer much expertise, but if all else fails, look into Wireplumber; it sounds like it's failing to make the proper node connections automatically.
