No click sound from song/click out-output...

[tomaskeys]

Hello!

I have recorded a backingtrack that is to be played during the intro of a song. The idea is that the drummer in the band will connect his headphones to the song/click out-output at the back of the Juno gi in order to hear the... well, click. However, there is no click at all.
I have done these settings in the System Menu (click/player):
Song/click: CLICK
Click level: 10
click sound: TYPE 4
song/click output level: 127.

Have I forgotten anything?
