[alsa-devel] Proper way to set SCMS copy prohibited bits on IEC958 S/PDIF

I briefly checked the code for the Delta1010 (ice1712) to see if there was a way from user space to force the SCMS copy prohibited bits on in the S/PDIF stream. I see the driver initializes the bits to 0. Is there already a way to do this from user space, or would I have to modify the driver to force them on (or use a module parameter)?
