In our audio device, the audio channels are not independent with respect
to audio formats and sample rate. The formats and sample rates available
for a channel depend on how many other channels are active, as well as the
format and sample rate these channels are using. For example, at a bit
depth of 24 and a sample rate of 96 Khz, only a single channel can be
used. But the device can provide 3 channels at a sample rate of 48 Khz.
CoreAudio and host applications should see only those channel, sample rate
and bit depth combinations that are possible? Does CoreAudio and
IOAudioFamily have a mechanism to support such dependencies? As an
alternate approach, could a device driver provide a custom configuration
dialog, opened by a host application through CoreAudio?
Thank You,
