OMG! I had exactly the same problem when I attempted to use a buffer of 512
samples. And now even with 1024, I still have that if I have multiple apps
playing sound on the device at the same time.
I had timed very carefully my interupts, and they were easily within 0.01
microseconds, but it was impossible to get the engine working with that size.
I will try with your 'cheat sheet' and see what happend.
It's a bit sad that the only way of fixing it is to just effectively cancel
the renowed super-duper algorythm that makes IOAudioEngine sooooo special ;-)
Did you also have bad mixed noise? like, perfect sound if only one HAL client
is playing, but bad quality (like if the sound is not mixed, but replaces the
samples in the mix buffer) if 2+ are playing?
