Fresh install of Fedora 42. MOTU 6 sound card was working fine post install. Recent update and reboot the other day, and now the sound card is not showing in the sources.
Has anyone seen this on their system? Any thoughts or suggestions appreciated.
Hi and welcome to 
Can you post the output of the following commands as preformatted text </>
fpaste --sysinfo-audio --printonly
wpctl status
journalctl --no-hostname --no-pager -b -g 'audio|snd'
sudo dnf history info last
thanks
Thanks for your reply Joe. Here is the output below.
The sound card is plugged in and is missing from the sources list, but you can see it under settings as the default device.

Does it show up under lsusb?
Does it show up as part of the output of cat ~/.local/state/wireplumber/default-nodes
Thanks
Not under lsusb , but yes under cat wireplumber
Can you run journalctl --no-pager --no-hostname -f
and unplug and plug the device in and see if you see anything interesting.
Does this device have it’s own power supply?
Have you tried another USB port?
thanks
Yes it has it’s own power source. Here is the initial output

Maybe it was just the usb port? Strange that it was working on that port before and then dropped out after an update.
I have been turning power to the sound card off when not in use. Maybe that is a factor
Not sure, that would seem like hardware if it works on other USB ports.
It is weird that it worked prior to that.
Are you running using fprintd for something? (fingerprint reader)
Does the behavior change if you stop and mask the fprintd.service?
systemctl stop fprintd.service
systemctl mask fprintd.service
I was not intentionally running fprintd. If I stop it before running the journalctl command, it still shows in the that fprintd is stopping in the journalctl output. It does not seem to change anything about the sound card.
The sound card seems to be working now, if anything changes I will report back.
Thanks for your help!
