How to configure Kaffeine to use jack

Hello All,
Does anyone know how to configure Kaffeine to use jack.

After I start jack with:

$ jackd -v -d alsa

there is no audio coming from Kaffeine.
Thanks

Kaffeine like other KDE apps will use whatever backend (usually gstreamer or xine) is configured in KDE System Settings>Multimedia>Phonon (Backends tab). Armed with that info, you can go to jackaudio.org and research your question there.

That website should save you starting a different thread for each application you are trying to use jack for. There aren’t many users on this forum experienced in using jack sound server for DAW applications. There are probably even fewer than that with experience in using jack for general-purpose media applications, including kaffeine.
