Yes of course ! physical input/output should be patched. Thanks. How could I've missed that !
Just to make sure : when you say that the following sentence is wrong :
"#3 : patch connections in jack : input -> jdelay, jdelay -> output, you should get a tone in your speakers"
you were refering to the tone part, right ? you mean that physical connections should ALSO be made, i guess. Because if there are no connections in jack such as I discribed signal won't get in or out, and thus Jdelay won't be able to calculate latency.

output connector of your soundcard to the PHYSICAL input of your
soundcard.
yes, because jdelay is sending a signal out of the soundcard expecting

it to come back, but you have not connected it so that it can.
