No microphone input after pipewire and kernel update

General system Gaming, sound and video

After the latest kernel and pipewire update I can no longer record audio from my Behringer UMC404HD interface. The input is detected in alsamixer, pavucontrol, etc but no audio is recorded. I restored a snapshot to before the update to start troubleshooting this and it works fine, but once pw, it’s plugins and the kernel updates it’s no dice. After a lot of prodding I stumbled into this

journalctl --user -u pipewire

I’m stumped, any help anyone can offer would be really appreciated

Can you try installing the lts kernel and see if it works?
I prefer using the lts kernel.

Welcome to the purple space!!

Thanks, purple space is my favorite kind of space but no joy. journalctl is still complaining about the device being busy. Thanks for the LTS tip, didn’t think of that. Now it’s narrowed down to the pipewire update possibly. Here’s the log for consistencies sake

If it broke after a specific update then it’s likely a regression in that update, therefore expect a fixed version to come “soon”.

You can downgrade back to the working version in the meantime.

Curiously, downgrading the packages doesn’t restore functionality

6

Looks like there’s more users with usb audio interfaces being affected

I can now confirm that the issue is definitely related to the latest 5.19.9 kernel. Downgrading to 5.19.8 restored normal function to my device.

8

It’s a kernel bug, the upstream bug report is https://bugzilla.kernel.org/show_bug.cgi?id=216500

9

But the lts kernel doesn’t?

10

Can also confirm this is a kernel bug, rolling back to 5.19.8 fixes it.

I had this lovely surprise yesterday upon a reboot myself

11

Finally stumbled on this thread after many hours of googling, thanks for posting to confirm!

No chance of changing configuration of audio-sinks in pavucontrol (in the Configuration tab, far upper right, mostly clicking > right is needed to get to the tab)?

Sorry, just asking, because that is something, many people miss to check.
