Hi all,
I am using ubuntu studio 24.04 and it looks like jackd2 has stopped working on a jackd client that I am using:
I used to start normally the jackd session as
$ jackd -dnet -C 4 -P 8
but I've been seeing these messages since last night:
jackdmp 1.9.21
[...]

I am mostly worried about this
"unknown driver net" messages, but perhaps the warnings are also relevant.
Indeed something is changed and the backends have vanished:
$ jackd --help
[...]

I found this topic https://linuxmusicians.com/viewtopic.php?t=19590 where reinstalling jack in arch fixed their issue..
I tried the same as
$ dpkg -l | grep jackd
$ sudo apt install --reinstall jackd jackd2 jackd2-firewire libjack-jackd2-0 libjack-jackd2-dev
but the issue persists. I assume some automatic update caused this but I wonder if anyone else has seen this and if you managed to fix it somehow.
Thank you in advance for your help
