Question about Optical audio to coax audio conversion?

Question

I'm trying to hook an xbox360 up to a surround sound system that only has a coax digital audio input and I just found out that I can get a converter that will allow the optical digital audio cable from the 360 to be converted to coax digital audio. Is there any signal loss in this conversion or will I get the full surround sound signal through the conversion?

Answer 1

The conversion is probably the changing of the transmission type from optical TOSLink optical to coax instead of changing the signal type.  

The signal will be in the S/PDIF format either way so it should just work without any kind of appreciable loss.

Answer 2

There is no loss of any kind through this conversion, as it is all digital.

Answer 3

I don't know much about xbox, but be certain that the conversion clock will convert the xbox properly.  Dolby digital bitstreams comes out at 192khz and most cheap converters only work to 48khz.  You'll have to downshift to PCM (44.1khz) to get any sound.
