If the source is HDMI, the HDCP rule book writes passthrough SHALL be stereo.
There's nothing busted here as it's obeying the HDCP rules. If I mis-read this and you are on OTA then there is NO PASS THROUGH and here it does give me 5.1 when OTA channels have that.

i have a blueray home cinema system model No hb905pa
connected to this i have samsung tv with hd tuner and also a humax hd satellite receiver both are connected via optical cables. my problem is when tuned into a hd channel showing 5.1 signal if i set the lg home cinema to bypass for multi channel signals i only get sound through 2.1 speakers. if i use the other settings eg pll movie i get 5.1 produced from a 2 channel source. my question is why am i not getting multichannel sound through the optical.or am i missing something. ps i set the sound from tv to dolby digital not pcm.
