Subject: More digital recording tests

All my I/O's labelled S/PDIF have RCA sockets whereas the one's labelled
digital have 3.5mm.
For some reason I thought i needed RCA into stereo 3.5, but a mono will work
ok. Does gold-plated make much difference for a digital signal, is it
limitation to my "prosumer" soundcard or Archos hardware?
------------------------

The specification for S/PDIF (IEC-958) calls for 75 ohm coaxial cable (or
fiber optic) with an RCA or BNC connector. With short cable lengths (less
than 10 meters) you can probably get away with all sorts of things like
phono jacks and tin plated connectors. However...

In looking at the specifications for the SB Live card I see that the Digital
Out connector (3.5mm Jack) is said to connect to FourPointSurround Digital
speakers, so this may very well not be a S/PDIF output, or it may be a 4
channel variant of the same.

I dont' think it's S/PDIF at all, or at least not the kind that the Archos
can use.
Try one of the devices you have with the RCA output.
