Hello Tim,
I share your frustration; since Windows Vista, the new architecture
caches the audio format in the registry and frequently ignores the
capabilities reported by the driver.
Have you tried KSEVENT_PINCAPS_FORMATCHANGE? It's only supported on
Windows 7, but that may be what you're looking for.
Cheers,
Matt

What I'm saying is that I am pretty well convinced this is not a
problem in my filter. I'm doing the right thing, in AVStream terms.
In the sysaudio/waveIn case, someone above me is deciding what my
default audio format is, and caching that information without
consulting me, and without considering that my capabilities might
change over time. That's what I need to nail down.
