Why? Secure Audio Path doesn't work anyway, not even as it's supposed to
work.

No. drmk.sys and drmkaud.sys heavily verify all involved modules, so you're
bound to MSDRM.

No. Technically, it would be possible, if you could inject your modules
into the DRM client part. About trivial, if you know how to
reverse-engineer, but for sure not legitimate.
