although clementine has the same issue as previously mentioned - it connects/disconnects between songs and disconnects when not playing.

RB can definitely use JACK directly (because gstreamer can). I did this for years. Alas, I've been using Clementine for years now too, and I do not recall the precise gstreamer setup I used with RB.

If you are fine with not using Rhythmbox, try Strawberry [1](a fork of
Clementine [2](inspired by Amarok [3])).

In the settings select "Backend". Set Engine to "GStreamer" and Output
to "Output to a JACK server". It will show up in the Graph of QJackctl
as it's own node and you can route it as you wish.
