I have a question

[Lachatiet]

J connected sooperlooper with "system capture" and with "playback" with help of QjackCtl.
How to do the same from command line?

You might be able to craft a command based on examples from these, and other links.

Why you are recommending resources on arecord (ALSA tool) while using JACK (Qjackctl) is a mistery.

You can use jack_lsp to list the current ports and jack_connect to connect them.

For example to connect sooperlooper common in and out ports to the the respectively system capture and playback ports:

Code: Select all

jack_connect system:capture_1 sooperlooper:common_in_1
jack_connect system:capture_2 sooperlooper:common_in_2
jack_connect system:playback_1 sooperlooper:common_out_1
jack_connect system:playback_2 sooperlooper:common_out_2

You can automate it with a rules-file and a permanently runnung jack-plumbing.

Or you can use jack_connect.
