Determining the maximum number of channels in use for a device

Hi,

For a multi-channel device, is there a way to determine the maximum number channels that have been opened by clients?

Something akin to kAudioDevicePropertyDeviceIsRunningSomewhere.

We have an audio device driver, where we want to apply some processing which can change based on whether only 2 channels are being used for playback or 6 (5.1) channels are being used.

Currently, the driver simply gets a mix of 6 channels, so we have no way of knowing if clients are using only 2 of those 6 channels.

Thanks.
Devendra.
