Yes, AUHAL won't do a rate conversion for you in 10.6. You can listen to the sample rate changing and reconfigure the AU to deal with that changing condition

Hi Bill

Are you saying that in 10.5 or previous AUHAL did do sample rate conversion in this case?

I didn't expect it to do rate conversion, I expect it to deliver the samples at the external clock-rate when it is synced to an external clock source. Is there a way to configure it to just slave to whatever the external clock is without having to stop it and reconfigure it?

Can I reconfigure the AU in the sample rate change notification callback? (ie reentrantly?)

Thanks

Ross.
