Problem with Set/Get volume of input device with single channel

Hi,

I am trying to Set/Get Volume level of Input device which has only single
channel but no master channel, then it fails to retrieve the
kAudioDevicePropertyPreferredChannelsForStereo and intermittently
kAudioDevicePropertyVolumeScalar for each channel. But this works well for
Output device.

So is there any difference in setting/getting the volume of input channels?

I am pasting the downloadable link to sample.

Thanks in advance.

Regards
Mustafa
