The HAL creates a device for each IOAudioEngine a given IOAudioDevice
has. In your case, I would expect to see a separate IOAudioDevice (with
however many engines your devices have) for each card in the box.

Hi,
We have an audio device driver (kext) for a PCI sound card that works
fine as long as we have one instance of the device.
When I plug in two of these cards - two instances of the driver objects
are created, initialized, etc.. Everything seems to work fine, except
that the CoreAudio HAL only reports the first instance.
Can anybody tell me what I need to do to get the second instance
recognized by CoreAudio?
Thanks.
Devendra.
