Works with Sonos - Pioneer SC-LX904

Sonos Port and Pioneer LX904
Set up the Port on the Pioneer, when i start playing on the music on the Port zones 2 and 3 turn on and play music.  problem is the zones do not turn off, so the amp stays on.  I have the auto power off enabled on the pioneer.  seems like the port doesn’t tell the receiver to shut down the zones that where turned on.  thoughts?

edit: i feel that the port should have been designed with hdmi port, which has native power management…  would be nice to have video as well.
