The upgrade to 41 has destroyed my video call capabilities. How can I get back to 40?
Obviously, the new kernel lacks the drivers for my webcam (General) and my external sound card ( Creative sound blaster. So neither the webcam nor the sound is available for calling.
I don’t have the money to buy new hardware, so I want to get back to v.40, where everything worked fine.
How can I achieve that?
No, I don’t want to reinstall. I have spent hours and days to configure my workplace.
I think it is just the new kernel where not supports your hardware, alias missing drivers for the new one.
You can test with the older kernel. By default there should be 4 in total saved for fall back.
While booting you can press the ESC key to see the boot options you have. Please test and give feedback.
You can not go back.Please do the above and give feedback.
Hi and thanks.
Have done. There is one option in the boot menu which says Fedora 40. When I boot that, the camera is working. But not the audio.
I have also tried a different external sound card. Result: Works sometimes.
Meaning even when it works initially, the connection is lost once I open the video conference app (using Google Meet).
Besides, I have 2 ideas what could be the problem.
a) I am still using Plasma X11. Not Wayland
b) How many USB ports can such a system manage? I have quite a few. Perhaps what used to be called an IRQ conflict in the olden days?
Ok, now I have tried all the session options I have on the login screen:
-Gnome under Wayland
-Gnome (Wayland)
-Plasma
-Gnome under Xorg
-Gnome
-Plasma (X11)
And run all updates.
Effect: Zero. The Webcam is not available. And the Audio devices give me ‘invalid status’ when I try to test them.
And when I fire up the Fedora version called 40 in the startup menu, I do get the camera, although when I check the system info it tells me I am v41. But the issues with the audio are the same. I see the devices in the pulse audio interface, but they don’t work. Same error. And this with 2 different external sound cards.
Running out of ideas now…
This is ok, as long it works. X11 is not actively developed anymore. Focus is on Wayland.
Nowadays it is less IRQ conflicts than a power issue. A USB port can deliver a certain amount of power. On external connectors, you can loos power because of the cable length.
USB3 is not so much a problem as USB2. Use connectors direct on the computer main board and see that you not overload a specific USB HUB. With lsusb you can see what you have.
So you might give some more info’s about the system to find the culprit of your errors.
That is an indication that you are experiencing problems with a recent kernel…
Would you know how install an older kernel for f41? for example this one: kernel-6.11.9-300.fc41 | Build Info | koji
Overview of older kernels released for f41: Fedora Updates System
Well, I have never done that…
The kernel you mention (xxxx 300) is still in my start-up menu. When I fire up that one, the camera works, but not the audio. Not even the microphone of the camera.
So the 6.12.04-200 kernel took away the camera. But the audio is a different issue.
The 6.11 Kernel Series are EOL (End of Life). If you want to try an older kernel I propose you to use the LTS Kernel. With this kernel you will still get security updates.
https://copr.fedorainfracloud.org/coprs/kwizart/kernel-longterm-6.6/
Ok, will try that. I see that the link tells me how to do it. Great!
Just for peace of mind: I do have backups of all my data. So i feel confident to experiment with the kernel…
when installing additional kernels for testing, make sure to increase the number of kernels the system retains, dnf is not deleting a kernel for every new one. How can I change the number of kernels retained when updating in Fedora? - #2 by augenauf describes you how to increase that number. (I would set it 5 or even higher, depending on the space available on your /boot partition).
the suggestion to hop onto a working 6.11.x one is to stick to it only until the issues are solved in 6.12.
Thanks for explaining. My mainboard provides about 10 USB connectors, some USB 2, some USB 3.
I have done some tidying up, and made sure that the problem devices are connected appropriately. That didn’t help.
Plus I have decided to go with Wayland, and it’s not really a problem as far as I can see. Haven’t checked all my apps yet. I knew ‘Autokey’ wouldn’t work, but found a way around that.
But still no improvements on the audio front. Has Fedora switched to a different audio base? Or is Pulse supposed to work?
Hi again. Tried this. Now runnung the kernel 6.6.64-200.fc41.x86_64 (64-bit) in my Plasma Wayland machine. Unfortunately no imrovement. Both devices (camera and sound card) are recognized according to System Infor. This is the list of my USB devices:
Thanks for pointing me to thekernel list config. For some reason, It was not in the dnf5 directory. But I found and changed it.
Regarding sticking to the 6.11.x kernel: That is not really solving my problems, as the audio still doesn’t work aslo in that kernel.
But audio seems to be not working regardless of the kernel. So perhaps it is some other issue, having to do with Fedora 41´?

OK, a short update. I found another Webcam in my drawer, and that one works! Also under the latest standard kernel 6.12.4-200.fc41.x86_64 (64-bit). And seemingly reliable. So maybe the other webcam was just too old?
However, the audio problems remain. No audio from the webcam, no audio from either sound card. Be it line in or microphone.
So I guess the focus issue is the audio now.
Was on the verge of giving up with Fedora KDE Plasma, but if the camera keeps working, I will put in some more days of trying…
Although in a way this doesn’t make sense. I want a computer that works, not a computer that requires weeks of work after a software update.
I have just checked. The webcam that refused to work was the Sandberg 133-97 The seller says it is not compatible with Linux. Weird, because up until Fedora 41 it worked perfectly, Linux Mint and Fedora since v38. But now we suddenly have problems. So someone forgot to add the driver to the latest kernels. Too bad!
As mentioned before, my camera problem is solved by using a different camera.
Which leaves me with the audio topic. (Which is equally important).
And the question: Am I better off using a LTS kernel or should I go back to the standard one? Both do not make my sound work, so ther eis no prefernce really. Do I understand right, that the LTS kernel is considered kind of stable, that is will not receive that many updates, while the curent kernel gets lots of updates - so at some point in time it has better chances to work with my audio equipment?
If this assumption is correct, I would probably want to revert back to the standard kernels. How do I implement that?
Boot into an other kernel than 6.6 and remove it with the command:
sudo dnf remove kernel-longterm
when everything is fine you can deactivate the repository with:
sudo dnf copr disable kwizart/kernel-longterm-6.6
As a help might be useful to see how you can use grubby to change the alias of the default kernel.
