Optical Protocols?

[evandy0]

Does anyone know if an ancient Sony CD-Jukebox (CDP-CX55) might be putting out something other than PCM from its toslink port? I am trying to diagnose why my new Onkyo receiver won't detect/decode the optical signal, and this is the only thing that I can think of, as:

Optical cable plugged into old Yamaha HTR-5750 works fine.
Another device plugged into the optical port on the Onkyo works fine.

I'm thinking that I might have to live with stereo cables unless I want to replace my CD player.

Hi, Evan. I'd be suprised if there was a change in the protocol that was causing this. A couple of questions:

1. Are you using the same optical cable every time?
2. What is the model number of your Onkyo? I'm wondering if you have to change a setting for the PCM to get it to recognize it correctly.

EDIT: Never mind on the model number - I just saw your other thread about it being a 709.

What's the digital output of the device which does work with the Onkyo's Toslink input. Remember, some receiving devices must be in sync at the lowest common denominator with the sending unit, so see if the Onkyo's Toslink input is adjustable at the unit's menu from DSD to PCM and/or bit/sampling rate.

DSD cannot be output via optical and this player does not appear to be a SACD player as far as I can tell, nor does it appear to have video output. This would almost certainly mean PCM is the only option coming out of the optical port, so something is likely wrong with the output.

Are you using the same optical port on the Onkyo for the Sony and the other device?

I would check the Onkyo's menu to make sure the digital input is set to Auto.

Hmm.. My Panasonic BD-80 sends bitstream or PCM via Toslink or coaxial S/PDIF. Perhaps, I used DSD when I should have said bitstream, instead.
