Disabling SCMS copy control on PCM2906C S/PDIF input

Isochronous-in data is affected by the serial copy management system (SCMS). When the control bit indicates that the received digital audio data is original, the input digital audio data is transferred to the host. If the data is indicated as first generation or higher, the transferred data is routed to the analog input. Digital audio data output is always encoded as original with SCMS control. The implementation of this feature is optional. It is the designer’s responsibility to determine whether to implement this feature in a product or not.

I have attempted to use a 2906C with an AES/EBU digital input signal.  Converting the higher-level AES/EBU (differential) input signal to be compatible with the single-ended S/PDIF input of the 2906 is easy....but getting the 2906 to ignore SCMS copy restrictions is not.  In many cases, the 2906 would not accept the digital input because SCMS flags (or whatever) were set.  We'd like to completely disable the SCMS detection on the S/PDIF input if this is possible.

Any info on this would be appreciated.....
