Hi Alex,
You are right, providing names is optional. I'm not concerned about
drivers that do not implement these properties.
Please read my note carefully.
What I'm talking about is the situation in which the driver *does*
implement the property, yet CoreAudio does not let an application access
it using one of the documented mechanisms.
BTW, the driver does not implement two properties - it's the same
property, which can be accessed in two ways. Either by retrieving pointer
to a CFString object or by retrieving a null terminated string.
Now, In cases where the driver *does* provide the property, CoreAudio
allows retrieving it as a CFString, but not as a null terminated string.
And that's what I consider a bug in CoreAudio.
Thanks.
Devendra.

Hi Devendra,
3rd party CoreAudio drivers are not required to implement either of the
below properties, and many do not - it's not a CoreAudio bug, rather a
driver deficiency. AFAIK, it is something that you can't rely on
being implemented when you query the driver.

Hi,
I have run across a situation which might be a bug in the CoreAudio
(framework?).
This has to do with the audio device property for channel names.
If I try to retrieve the property using
kAudioDevicePropertyChannelName
it will not work.
However, if I use
kAudioDevicePropertyChannelNameCFString, it works
just fine!
Should I file a bug report, or am I missing something here?
Thanks.
Devendra.
