kAudioDevicePropertyBufferFrameSize != inNumberFrames

Greetings,

I have finally figured how to alter the frame count of the Default Output Audio Unit, using the kAudioDevicePropertyBufferFrameSize property. It was normally 512, but now I am changing it to 256. The property setting function returns no error, and if I again retrieve the kAudioDevicePropertyBufferFrameSize property from the audio unit, it continues to be set at 256. However the inNumberOfFrames argument in the render callback is 236.

Does anybody have any ideas as to why that is?

Thanks!

Aristotel
