Onkyo TX-SR502: problems with surround sound

[canuck94]

So I just took another stab at messing with my surround settings. I simply can't get them working right. I'm running with a 5.1 setup. I get proper sounds out of all speakers but all the ambient surround sounds are broadcast equally from all 4 surround speakers. It's like I'm getting quad channel surround mono.

- I've got an optical audio cable connected between my EVA media streamer and the amp.
- The audio signal on the videos I'm testing is "Dolby Digital, 48KHz, 6ch".
- I've tried all 'audio modes' (none of the DTS or Dolby modes appear as I cycle through the modes; they never have).
- When I use the 'test tone' function all 5 speakers broadcast correctly.

For convenience, here is a link to the pdf manual. Perhaps you can spot something I'm missing.

I have no idea what an EVA media bit streamer is. But how is it set to output? I suspect that is the problem. It probably is sending a signal your receiver can only process as multichannel stereo which is awful.

Do you have a DVD player or BD you can set up. Set the player to output bit stream. Can you set the EVA to output bit stream? I hope so. Check that manual and see what the output selection is. My guess is the wretched thing is outputting multichannel "stereo" PCM, and the receiver is doing what it is supposed to.
