I connect any USB device after reboot and it works fine. After reconnect ALSA shows the device but it does not appeared in Carla (ant qjackctl). I have to reboot to use device.

For example

$ aplay -l

Assigning this to Ubuntu, not UbuntuForums, as this is not a forums issue.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.

Ubuntu 21.10 (impish) reached end-of-life on July 14, 2022.

Is this still an issue when using a currently supported release of Ubuntu? If so, please execute the following command only once, as it will automatically gather debugging information, in a terminal:

  apport-collect 1967615

and then change the status of the bug back to 'New'.

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Hi. Same issue in 22.10

$ cat /etc/issue

$ jackd --version

Sometime devices (after several unplugs and plugs) present only in Alsa, but jackd (Carla) does not see them. No errors in logs.

But interesting thing is that MiDi controller present in jackd although soundcard (audio ports) not
