Hi -

System: G5 dual - with the built in audio device:

If I call AudioDeviceStart successfully and then immediately query
kAudioDevicePropertyDeviceIsRunning property, the device does NOT always
report that it is running. I have had to wait 100 to 1000ms before getting
the proper value from the device.

When is the device officially running - after the start call or only after a
callback has occurred or some other time? The documentation says that a
callback will likely occur before AudioDeviceStart returns but there is no
guarantee of that.

Can anyone describe what I should be able to expect?

Thanks
Jimmy D.
