Slight correction may be in order here…the target of your ire should probably be the conservative fundamentalists (aka Y’all-Qaeda) in the US; the Satanic Temple folks are generally atheists and seem pretty chill to an outsider like me.

Just as an update to this, I noticed that there was a new version of gnome control center (49.4-2.fc43) in the latest update push for Fedora so I took a chance and did the upgrade hoping it would include a fix to this issue. Based on initial testing on my two machines at home which were affected and needed to be downgraded to 49.1-1.fc43, it looks like this new version resolves the line-out audio problem. Thanks again for your efforts to raise awareness of this and your suggested workaround.

Hey I tested the downgrade script and it fixed my issue just like you suggested. But of course now my OS wants to update the files back to the version I rolled back from. It doesn’t seem to be a forced update and I updated and upgraded everything before I tried this but I was wondering if the issue will immediately return once I allow the system to go back to version 49.4-1.fc43.

Doesn’t look like there is any way to skip those file updates so I suppose I just need to do the downgrade again if the sound problem returns? Hoping the next revision of gnome-control-center resolves it.

Thank you again for your efforts and information sharing. This is what I love about the Linux community and it is making the transition from commercial slop-ware so much easier.

Thank you for working through this and sharing your findings. I will try this out tonight.

I am seeing the exact same issue on a PC I just put together and loaded Fedora 43 Workstation on. If I hook the 3.5mm jack for the speakers (older Creative Pebbles) to the green port on the back panel it shows up just like OP’s when I try to test; however, if I plug the jack into the headphones port on the case (which is connected to the motherboard audio pins) it detects and works properly. I was also seeing some Dummy Output options with the line out connection in use, and not knowing what it meant, I selected one and this kicked me back to the login screen and gave me an unhelpful kernel alert.

In contrast, the speakers on my other PC, which is also running Fedora 43 Workstation, works fine off of the back panel. Both motherboards are using Realtek audio chips but it may not be the same version since one board is a B650 and one is a B550.

Curious to see what the solution ends up being but I also recently installed pavucontrol on the newer PC so I will try and set the speakers up using the line-out that way. If that doesn’t work I will migrate to bluetooth speakers or just leave things as is.

This is really interesting. I started with Mint-Cinnamon since it sounded like it would be ideal for me as I had no desire to switch to Windows 11 and I needed a daily driver OS; I did not like Mint at all and spent too much time trying to make it work with newer hardware. Fedora Workstation has been a great experience for me and it checks all the boxes with minimal troubleshooting. What is about Arch that made you decide to switch? Genuinely curious as I am all-in on Linux now that I know I can do productivity stuff and gaming so easily and I don’t have to give another dime to MS.
