To change the sample rate on any device, aggregate or otherwise, just
set the property, kAudioDevicePropertyNominalSampleRate. For an
aggregate device, this has the added benefit of changing the sample
rate of all the sub-devices in one call.

We have code that use the AUHAL and possibly uses an aggregate

device. We do that with the following code:
When actually changing the SR value, 1) succeed but 2) fails
already in " Check ouput sample rate" part: we get an
"kAudioHardwareUnknownPropertyError" error.
Is this a bug? Is this way of doing obsolete?
