I have an issue, there's certain actions that cause it. Two very consistent ones are any time I join a voice channel in discord, and when I launch new Wine processes, specifically World of Warcraft. My audio devices appear to re-enumerate somehow.
It's not producing any sort of error that I can see, just more what looks like output about the aftermath. Dmesg doesn't seem to show anything, but the user-level journalctl shows some output from kde's pulse components about "no object for name" for various audio devices as it re-enumerates. The lack of output in dmesg makes me think the audio device I use (Razer Kraken V3 X) is not disconnecting. Sound during this time would blip, but does continue to work after.
Normally I wouldn't have mentioned anything at all other than passively trying to figure out what's happening, but Discord has decided when this happens, it's going to dump core, and frankly I don't blame it, the amount of times I see the little toast from KDE about the active audio device makes me think whatever it's doing it's doing a few times.
I'm using X11 and KDE/Plasma.
In this snippet, I opened Discord, opened Konsole, and then joined a voice channel.

Warning: removing 1 bytes from stdin
Parent is shutting down, bye...It struck me that it was happening when I joined a voice channel and when I open World of Warcraft via Wine (which has voice capability) to on a whim, I opened Audacity, and that too triggers it.
EDIT: an additional datapoint is Audacity -> Audio Setup -> Rescan Audio Devices also triggers it
TITLE EDIT: Due to finding it seems to be triggered by microphone access (joining a discord voice channel, launching WoW which does touch the microphone) and does not happen with the same physical headset on another Arch machine that uses Pulse, rather than Pipewire (which I have to use on this system), I've changed the title to more accurately reflect the issue as I've identified thus far.

I've been going through forum topics looking for anything similar, the pipewire involvement, and the trigger (applications that can use microphone input) looks very familiar, though pipewire doesn't appear to be crashing in my case.

Searching around more, I also found this: https://bbs.archlinux.org/viewtopic.php?id=299332
Considering the timing, I gave removing ~/.local/state/wireplumber a try
This appears to have fixed it.
