No, the Media Feature Pack doesn't fix that. Microsoft broke S/PDIF with the Creators Update and when I updated a while after its release I was afraid for the thing that's actually happening. Waiting for a fix takes months. They broke SPDIF before. Twice (only the one time it got through and the other time they catched it on time). They did make a fix but it's only available for the Inside Preview builds 16184 and up. The other time took over 7 months to fix.
I actually don't want to install Inside Preview, but don't want to downgrade either. But that's not a solution. I wonder what makes it SO darn hard to fix such a feature. Just hotfix it, you'd say.
Anyway, I have to agree with the latest posts. This talk kind of doesn't belong here, since this thread is for unlocking audio drivers in W7, 8 and 10.
