Re: [Csnd-dev] csound and jack

Hi!

This is probably not comforting - I am using jack for all my audio work
with no problems on openSuse (15.4), mostly with qjackctl. I find it great,
especially due its flexibility to connect/patch  any jack-aware software.

 Might be that there is something special in your setup or some
configuration is changed some peculiar way that stands on the way. Hard to
tell.

Can you try to run jack in dummy mode to see if it works by itself and if
Csound (for example) or any other softeware can connect to it?

This is a screenshot of the qjackctl settings:

Another thing you can try to kill pulseaudio:

pulseaudio -k

Pulse restarts itself after that but it might clear something.

Not sure if it helps...
