Yeah, having 1.7c in your unit is a good thing.

"Good luck, but I think you may have more luck figuring out the 1.8c format."

I already know the format isn't:

Left Justified 24 bit
I2S 16 bit
I2S 24 bit
Right Justified 24bit
Right Justified 16bit

Those are all the formats supported by the transceiver cards and my original digital output cards and all the formats supported by the chips I am using in each of those cards in the mode I run the chips in.

Up till now everything has been either 24 bit I2S or 24 bit left justified format. Figuring out the format alone would not be enough, it would also take new hardware that supported that format. As far as I can tell most SPDIF transceiver/output chips only support the modes listed above in hardware mode.

Cypress emailed me back looking for more information about why I need the earlier firmware. Will see what happens there.
