I seem to recall the iMic always reported sr = 0...

On Panther we were using the kAudioDevicePropertyStreamFormats
property to get information on all supported formats, then read the
mSampleRate field to get the supported sample rate for each of the

On Tiger when used on an agregate device built with the USB iMic (so
that the 2 input/output internal device appears as a single device
easier to handle) twochannels can be retrieved but both show a sample
rate value of 0!
Is this behaviour a bug ?
I see that HALCode is using the
kAudioDevicePropertyAvailableNominalSampleRates property to get the
sample rate values.
Is this the recommended way of doing?
Thanks
