I am experiencing audio reconnect every 30-60 seconds, showing the device name on the screen as a pop-up each time.
I am running a fresh Fedora 40 install on plasma 6 (I moved from Ubuntu 20.04, kde 5 recently, and got the same problem there as well).
uname -a gives me the result:
Linux fedora 6.10.8-200.fc40.x86_64
My audio cards are as follows:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0

I am connected to the ALC887-VD Analog device using headphones, I have tried multiple different wired headphones and tried connecting to both the front and back connections.
The HDMI 0 device seems fine (sound is constant through the screen).
Running journalctl -p 4 yields loops of the following errors and warnings:

With the pipeplumber being an error, the other are warnings.
