One thing you might run into though is that to maintain an ~11.5ms

frames to 2048 frames.
Dumb question just to make sure I'm following you: Which buffer are
you referring to here?
If this is the case, you probably need to update each AU's
kAudioUnitProperty_MaximumFramesPerSlice property to be large enough.
Are there guidelines for how to make sure we're setting the
kAudioUnitProperty_MaximumFramesPerSlice to ensure that it is the
right size for a particular I/O cycle of a particular device? The
way you phrase it above makes me think there is a straightforward
calculation that will give the right answer, but if so I'm ignorant
of it. (This is probably related to my ignorance of where you got
the 11.5ms number for the I/O cycle.)
Cheers,
Christopher
