I don't care which.
I rely heavily on Jack and run complex routes and cannot live without
it, but I must ask why you want to use jack? Do you really need it ?
I need to run LV2 plugins.

Which of the cards Generic or Generic1 do you want to connect to with
Jack ?

Do you use pulseaudio ?

Regardless;

Here is something you can do to try and make jack work with alsa

!) Close qjackctl, as it doesnt work for you. I avoid it like the plague. It helps me none and just causes problems.

2) execute the following in a user terminal

$] pulseaudio -k
$] killall -KILL jackd
$]  /usr/bin/jackd --sync -P80 -ndefault -dalsa -dhw:Generic -r441

Post the complete terminal output from the last /usr/bin/jackd command




/usr/bin/jackd --sync -P80 -ndefault -dalsa -dhw:UMC1820 -r441
