U are talking about a solution above, can U help me? Maybe I'm doing something wrong, I would love some help here.
two small thing:
1. voltage level conversion might solve your problem with integrated sound, the signal's strength might not enough for the receiver

(Coax to TTL)
2. if you connect directly the spdif signal from soundcard to the receivers pin, this can cause groundloop and noise problems. an 1:1 line transformer is the best solution between them...
