Just to let everyone know, it looks like the I2S signal from the RioReceiver is incompatible with the CS8405 transmitter chip used in the RioCar S/PDIF board. Another chip will need to be used. Perhaps a CS8420. This will have the added benefit of jitter reduction if it works. Costs, will go up a bit though. This chip costs 3x the CS8405.
