Another issue I've run into is that not all Macs capable of running Boot Camp have the actual Intel CPU chip in them some of the Macs had that simulator running on the Motorola CPU. 'Cause for $200, you could buy yourself a pretty good refurbished Dell desktop with W7 on it and easily upgrade to W10 and then run your SCD2 app on a native PC instead of a simulator. Does the SCD2 come with a list of compatible Mac sound cards or on their website?
Are you planning on swapping out the Sound card if discrete or paying a licensed Mac Tech to do so? If it's a discrete card swap-out, you're probably looking at $200 or more to do the swap-out of the hardware. (I used to have them 20 years ago, but got out of fixing Macs). And you need special tools to disassemble them. Have you contacted the software maker of SCD2, to see if their program is W10 certified? Mac repairs are quite expensive compared to PCs which I'm sure you already know. It would be helpful to know the exact Mac model you have, since there have been so many of them. Is your Cirrus Logic a discrete card or a chip? Generally speaking, Mac hardware is not removable except on older Macs such as the Quadras, certain iMacs, etc.
