Fader Automation

Hi all, ive got a little problem when trying to automate more then two speaker panning.
I can record my panning in the automation Tab but when playing back (automation set on playback) no sound comes out of my speakers ?
Any hints what im doing wrong?

2 Speaker panning automation is working as aspected.

thx snowder

it was answered on IRC. VBAP panner automation is currently not implemented.
