Audio driver starting delay

Hi,

On a Mac mini intel, we see a several second delay between the call to "AudioOutputUnitStart" (we are using AUHAL to drive the real driver) and the first time the audio callback is called. This delay seems also to depend of the underlying driver we are using (less for MOTU 828, more for Built-in). This behaviour was never seen on PPC machine (G5 for example).

Is this a normal behaviour? Is there a simple way to be sure the driver is really running when we get out of our "Start" function? or do we need to implement a synchonization procedure ourself?

Thanks

Stephane Letz
