Not exactly. If you want to use the *multi-channel* analog outputs, then you need to disable HDMI audio out. HDMI audio can be used concurrently with analog output if you want multi-channel over HDMI and 2-channel over analog.Make sure to read the review in this thread. It appears that if you use the analog out you have to disable the audio out for the HDMI. That would force you to always use your reciever when using the 55.
But for this particular poster, he could use the 2-ch+5.1-ch outputs (both analog) if he wants to hook up 5.1-channel analog audio to the receiver and 2-channel downmixed audio to the TV directly.
