Folks, Greetings!
I'm
purging deprecated functions from some Core Audio code & ran
across this line:
status
= AudioDeviceGetPropertyInfo(device, inChannel, true,
kAudioDevicePropertyVolumeScalar, NULL, &isWritable);
As far as I can tell, it gets replaced by:
Boolean settable;
AudioObjectPropertyAddress theAddress = {
kAudioDevicePropertyVolumeScalar,
kAudioObjectPropertyScopeGlobal,
kAudioObjectPropertyElementMaster
};
OSStatus
status = AudioObjectIsPropertySettable(device,
&theAddress, &settable);
Is there a way to specify which channel I am asking about?
Am I worrying too much?
Thanks in advance for some illumination on this subject.
Peace,
Bob
