If You have service manual, i can check.
But anyways, you need to convert i2s to spdif.

i don't know better so if you can help please do.

As you may see in diagram, its input, signal goes to the digital input selector and then to the audio processing part.
Use pin90,92,94,96 and convert i2s to spdif.
