since the bt says is something in pipewire is probably a plasma-pa issue

> since the bt says is something in pipewire is probably a plasma-pa issue

huh, that's weird cause, cause this started happening after I installed pipewire (but I thought it was unrelated as there was a big batch of updates, too), but continued happening even after I uninstalled PW
There might be some leftovers of PW causing this, then, sorry

Doesn't Fedora 40 ship PipeWire by default? Did you have it masked or something? Starting to feel like a local configuration issue.

Well, uh
it's a long story, I'm a Linux beginner and therefore this is most probably a local configuration issue, apologies

I installed PipeWire thinking it was just an app or something, and that broke my audio configuration, so I uninstalled it (and then that broke KDE), found out it didn't fix my audio issue, then read that Fedora 40 ships with PulseAudio and so i swapped PipeWire with PulseAudio, and that fixed my broken audio, but I had to reset my KDE desktop

This report probably should be closed or set as Resolved, but I cant figure out which category fits "User error/local config" the most, so I hope "Not a bug" fits it well?
Again, I'm really sorry for this and for wasting your time, I thought it was a KDE issue and my reading through the backtrace didn't catch the fact that it was from PipeWire, apologies.

Sounds like a local configuration issue, yeah. NOT A BUG is fine.

In general — and especially when you're a beginner — it's best to ask for help when you encounter a problem, rather than trying random things that a web search (or even worse, ChatGPT!) suggests. The problem here is that you won't understand any of the information you find, and will lack the context to understand which of them will break your system (because the person writing the advice was using a system that isn't the same as yours such that the recommendation won't work). So since you're using Fedora, asking for help from other people also using Fedora is the best plan. Each Linux distro is really its own OS; advice you find for someone using Ubuntu likely won't be applicable to Fedora, for example.

Yeah, I'm starting to realize just how different the troubleshooting process in Linux is to Windows, and that you can't always expect the OS to catch your mistakes and not let you break almost everything if you just asked nicely
Thanks a ton, though!
