Pipewire intermittently doesn't show any sound device

Ask Fedora

Hi,

since yesterday, I have the issue that all my audio devices (input and output) have disappeared in the sound settings of Cinnamon. I assume that the issue though is at lower level and the sound settings are a consequence (see below). Rebooting solves or not the issue, or make it appear again. I had one case where the issue disappeared during a working session (for no apparent reason). As I write those lines, the problem is gone, but it was also gone yesterday, but it appeared again on first boot this morning.

The problem wasn’t there 2 days ago, and I can’t remember having done any change between the two days (dnf history shows that no update was done in-between).

While I have the issue:

  • pw-dump hangs forever
  • pw-cli ls hangs forever, interrupted it shows sometimes some devices, but only virtual ones.
  • aplay -L hangs sometimes forever, but sometimes it also shows the devices.
  • and so does alsa-info.sh (on cat /proc/asound/card1/codec#0 /proc/asound/card1/codec#2 )
  • lspci, lsusb and lsmod all seem to show the right thing
  • systemctl --user status pipe* wire*shows both pipewire and pipewire-pulse green (service and socket), as well as wireplumber, also green.
  • dmesg and journalctl don’t show anything suspicious
  • login and rebooting hang here and there, but I guess that it’s a follow-up appearance

Pipewire doesn't actually recognize any Sound outputs (devices) looks like my issue but it’s old, and wireplumber has replaced pipewire-media-session, so I do not think it’s really related.

As I have PCI and USB devices, I’m tending to think that it can’t be a hardware issue, but what do I know?

Any idea how to debug further is welcome, this is hanging over my head as it can reappear after every reboot.

Thanks, Eric

BTW, last kernel update was 5 (working) days before the issue appeared, and there was no pipewire/wireplumber upgrade since I moved to F41 (end of November).

But I have upgraded since the probleme appeared (8th of January, at 9:00), without noticeable effect:

The problem hasn’t appeared today but is still looming…

hello. I have had the same issue on Fedora KInoite 41. I am still trying to find out what is the issue. It usually happens after hibernation and then when I reboot the audio devices are back. It seems to have happened some time after the 20th of january as far as i remember because the image from that day and earlier didnt have the issue.
