spdif sample rate

When using 'Sound Input Configure' with a regular analog audio input from my sound card the sample rate request is the sample rate I get data at and everything works fine.

 

When performing the same action with an SPDIF input the sample rate I get will be whatever the sample rate set in the windows sound utility is.  Even stranger is that if I request 1 second worth of data from 'Sound Input Read' I will get FS samples every 1 second, however the data will be incorrect in the sense that its frequency shifted but also contains the occasionaly sinc pulse.

 

The only way to get correct data with SPDIF is to set the sample rate in the windows utility, and in LabView, to matching values before starting.
