Hi Sonny,
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. It would be helpful to know the exact Mac model you have, since there have been so many of 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. And you need special tools to disassemble them. (I used to have them 20 years ago, but got out of fixing Macs). 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. Does the SCD2 come with a list of compatible Mac sound cards or on their website?
'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. 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. In that case, you would have to replace your Mac with one that came with the Intel CPU chip on the Motherboard and try running the SCD2 app in Boot Camp mode. That would be a
LOT more expensive than just getting a used Windows PC and upgrading to W10.
Another thing you can try is if you have a PC lying around or that you could borrow from a friend, neighbor, family member, etc. you could download your app and test it on their W10 (maybe bribe them with a 6-pack of beer!). If the sound doesn't work on that W10 PC, it could be that the SCD2 app wasn't fully compliant with W10, or at least their audio codecs and drivers weren't written properly. In this case, it wouldn't be worth all the trouble to try my above solutions (swap out the Mac Audio Card if it has one, or buy a used W7 PC and upgrade to W10). But, at least you'd know it's a problem with your app, W10 incompatible etc. for the price of a 6-pack!

Is there a similar app available for a paid license or a free trial version from a different company that you could use?
Those are my thoughts. Perhaps one of our Mac gurus can chime in with another opinion.
