I would like to do this because my amplifier (Denon AVR-3801)
has only one coaxial digital input and I am already using that for
from my motherboards sp/dif output for listening music, etc.

For avoiding the sound forwarding I have considered buying following 
connector

   http://www.usa-x.org/1shop/product_info.php?products_id=105

which would contains both video and sp/dif output from the J2.

The problem is that 3 digital inputs in my amplifier which are still free
are all optical and I do not know is it possible to convert the electrical
sound signal from the usax connector to optical format.

What is this byteway this TTL sp/dif, does it differ somehow from the 
common SP/DIF format?
