Just a short question i struggle with:
Is there a way to check if the AudioDeviceID i have is an aggregate device?
I’m not sure how i would check this because i didn’t found a corresponding selector which i could use with AudioObjectGetPropertyDataSize.
Thanks in advance!
So I have come up with a solution myself:
Get a list of subdevices by getting the property
kAudioAggregateDevicePropertyActiveSubDeviceListIf there are no subdevices it will set
OSStatusto something other thannoErr. If this is the case you can assume that you have an aggregate device on your hands.
