It has recently come to my attention that changing the sample rate
before doing off-line rendering is crashing at least one AU plug-in.
Therefore I want to be absolutely sure that this is not a host
problem.
Is it necessary to AudioUnitUninitialize before changing the sample
rate?
It is possible for an AU to support StreamFormat changes while
Initialized, but most do not (and should return an error if you try
to).
Yes, for stream format changes I do uninit and init but this question
relates to explicitly sample rate changes.
If I do this, the AU in question, does not crash but produces
silence instead and then the AU is in a weird state (e.g. does not
display properly any more).
Do you Initialize again after Uninitializing and then changing the
sampling rate?
Oh yes, definitely.
