Thank you Daniel for the info. Hope this error will be fixed in the next version.
Anyway, it seems to be a consequence of the screensaver messing the audio: every time the screensaver is activated, the default sink to HDMI is changed to another one (internal audio), but also the HDMI description is changed, adding to the trailing number of the device. Maybe this is triggering the issue in pipewire. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2092652 Title: Wireplumber service repeatedly fails with "attempt to concatenate a nil value" error in alsa.lua when handling audio nodes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wireplumber/+bug/2092652/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
