This link might be useful:

Look under "converting between AES/EBU and S/PDIF interfaces".

There are 2 main differences:

1)
SPDIF is unbalanced and can be 0.5v to 5v.
AES/EBU is balanced 5v.

2)
The signal pathology is different:
There are extra check and flag bits in AES/EBU.


No. 1 must be fixed, and the link does give some info, but you might have to intercept the SPDIF signal before it is attenuated before the RCA socket.
No. 2 does not have to be fixed normally. Most DAC's don't mind, though any that give status indications such as bit-rate, might show an error.

Cheers,
