Does your samsung blu-ray have analog outputs? I think most players with analog outs have have a setting that does not permit bistream of the mutlichannel track if the analog outputs are preferred. On my old Sony bluray it would send PCM stereo over HDMI if the analog output was prefered.

My only other idea is to troubleshoot for an HDMI handshake problem - disconnect everything from the outlaw except the bluray and tv and try. Disabling HDMI-CEC can sometimes change the behaviors for the better (at the cost of some convenience, possibly).
