What I'm getting at is that under Win 7, all the inputs look the same in SONAR, whether they are digital or analog at the interface. In my main Patchmix session, the physical input named "S/PDIF L/R" sends to "Host ASIO In 13/14", and Shows up as "ASIO ASIO In 13" on the drivers tab in SONAR. I've given it the friendly name "S/PDIF In", so when I open the drop-down to choose an input for a track, I see Left S/PDIF In, Right S/PDIF In, and Stereo S/PDIF In.
 
Like I said, I haven't tried WDM for a while, but the Patchmix session setup and presentation of the inputs to SONAR should work basically the same way. So the question is what "Host" input is the strip sending the physical S/PDIF input to in your Patchmix session?

But when I go to the "Contact us" page, I see they have posted this "qualifier"....

So I guess I'll forge ahead.....
