RXV 1500, I am unable to get 5.1 audio
Just got off the phone with Yamaha customer support, who were very helpful. The display on the amp, in the lower right hand corner, displays the source input, not the output. So, for example, you can be watching cable tv, and the cable tv is sending a 2-channel stereo signal to your receiver. Your amp shows only L and R. But since it has a processing system, depending on the processing program you have chosen it will probably distribute that sound to all five speakers. You will be confused, because you hear sound from all speakers but you only see L and R lit up. You will believe that you are not getting 5.1 sound. And you will be correct: you aren't, because the source is not sending you a five-channel signal. That's where I got panicked. So the Yamaha representative said, insert a DVD that you absolutely know contains a Dolby Digital audio. I inserted Shaolin Soccer DVD, went straight to a scene in the middle, and bingo! The center and surround right and left speaker lights lit up! So there is the 5.1 surround sound. It will light up when it detects that kind of sound from the source. Otherwise it will probably give you a sort of "fake" 5-channel sound that it creates from a 2-channel source.
Now the question becomes, are your connections getting the 5-channel sound to the amp correctly? I just confirmed that my DVD, connected with a Coaxial cable to the Yamaha, does get 5.1 surround sound, if the sound is encoded in the DVD. I have not tested this yet with video games or Blu-Rays; I will post again if and when I confirm that this works on a PS3.
