I didn't know whether this thread should be in the Receiver forum or the AV Sources forum, so I put it in both. If it's wrong, feel free to move it or delete one of them. I have a Pioneer 563A DVD/CD player and an Onkyo HT-R510 receiver (from their 760 HTiB) I have the player connected to the receiever with the 6 channel analog inputs/outputs. The player is set to output in 5.1 and I have the receiver set to Multichannel input, so that it knows to use the analog inputs and not matrix or simulate any extra channels. When I put in an SACD, I only get sound from the two fronts and the L/R Surround. I get no sound from the center or the sub. The CD says it is a 5 channel SACD (don't know if that means 5.1 or 4.1) so I should be getting sound from at least one of those speakers or both. Unfortunately I only have one SACD right now, and no DVD-A's so I don't know whether the same thing will occur with other SACDs or DVD-A's. However, just to test, I put in a video DVD and set the receiver to Multichannel analog input and let the player do the decoding. When I did this, the center and sub channels worked just fine. I would appreciate any help or advice. Thanks.
