I'm by no means an expert at home theater so I would appreciate some help here. I have an Onkyo TX-NR808 receiver and a Panasonic Blue-ray home theater system. The model is SC-BT300. I hooked up the Panasonic blu-ray player to my receiver via an HDMI cable. I connected the blu-ray player speakers straight into the receiver hoping it would work. The only speaker plugged straight into the Panasonic player is the sub-woofer. The connections on all these speaker cables had a special connector built strictly for the Panasonic player I believe. I went out and bought speaker cable to replace the provided cables so I could plug into the back of the Onkyo. To better explain it here is a picture of the back of the SC-BT300 As you can see only the sub-woofer is hooked up to the back and the rest is straight into the Onkyo receiver as seen here. When I am trying to use the blu-ray player only sound comes out of the sub-woofer but nothing from the speakers. I'm sorry if this is a completely retarted thread but I would appreciate anyone's help.
