This last release fixed a core dump problem that was happening during boot.

However one problem remains that is when you lock the screen and it turns off, once you return you will see wireplumber process using 99% of the CPU.  
This only happens if you have Firefox opened, didn’t test with other applications.

To fix, just close Firefox and open it again.

Is this happening only with me or you guys also noticed the same behavior?

I’m using Gnome here, everything is up to date.

> Greetings lovely community, After the recent wireplumber (0.4.10-3 -\> 0.4.11-1) update just from the other day, I’ve noticed on at least 2-3 occasions that wireplumber is using an excessive amount of CPU and will have my CPU run high, which also causes my GPU fan to start spinning like there’s a wildfire inside my laptop. I can’t yet figure out how to reproduce the issue, it seems to happen randomly so far as I can tell for the moment. When it does happen, I’m not doing anything other than brow…

It’s a known issue for a while now unfortunately as it affects my setup too, but there is a fix that is just waiting to be merged here: [https://gitlab.freedesktop.org/pipewire/wireplumber/-/merge\_requests/398](https://gitlab.freedesktop.org/pipewire/wireplumber/-/merge_requests/398)
