Can't hear samples in sample edit nor in sample assign

Hi there -
I have struggled to find out why I can't hear my samples in the trim-window in sample edit nor in sample assign (in the browser). Can anyone give me a hint to where I can find a solution? I would happy
In the browser I can hear the samples when I hit the connected pad, but I can't hear the samples in the sample pool nor in the browse-window (with the instruments, drums and so on).
And in sample edit I hear the sample when I go to the program-chooser, but not when I choose trim.

All the best,
Xyllo

Is monitor on in mpc?

Thanks guys for replies. I ran it through again today - AND I found out why!! In preferences/general/audition & preview/audition output I had it on Out 3,4. I turned it to Out 1,2. And there it goes. - Happy MPC owner - again .
