Actually, I don't know whether any of the apps I own can use mmdevapi.
I've been looking at it because I believe you are going to rewrite winmm to use it.

I fear it's quite low given the precise description that MSDN makes
of the ping pong mode.  That does not happen by chance.

I suppose few apps will depend on exclusive mode because MSDN says
that the user decides whether to grant it or not.  At most, it'll
be an option within an app's menu.
