Optical Cable not carrying sound?

by Race3KGT / November 1, 2010 3:58 PM PDT

My problem is that I am trying to hookup my old Aiwa CX-NAJ50 stereo to my Vizio E320VA HDTV with an optical cable but not I'm not getting any sound from the TV through the Aiwa speakers. I also tried hooking up my Toshiba SD-2800 DVD with S/PID to the TV, and the sound will not play through the TV either. Tried to enable pretty much every combination of audio selections for all hardware to ensure that digital was activated. I highly doubt that the Rocketfish fiber optic cable is bad, since whenever it is plugged into any of the devices, I can see the red light being emitted from the other end. So as my Vizio only has one S/PID connection, I would prefer to hook the Aiwa up to it for louder, deeper, and more variable sound, but whatever will work to get EITHER that or the DVD working with optical audio would be great. Anybody have a solution?

the OLD Aiwa CX-NAJ50. Don't expect it doing thing it cannot do. How about maybe just use the red and white audio connection instead.

Wrong inputs/outputs

FWIW, I always liked those old Aiwa mini systems. They generally work really well IME. Unfortunately, this particular Aiwa only has digital optical *out*. In order for you to have sound starting from the HDTV (or other component via digital output) to the Aiwa speakers, the Aiwa would have to have digital optical *in*. See p.21 of the online manual here-

Similarly, the Vizio won't accept a digital optical input from your DVD player, since it only has SPDIF *out*. See p.12 & p.25 of their manual here-

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
