How to implement a mono input on CY8CKIT-033A platform?

Hi,

All examples of CY8CKIT-033A platform are stereo input/output.

Now we are designing a product with mono input/output.

I modify all the bNrChannels setting of Audio Descriptor of the USBiAP component, from 2 to 1.

Then I rebuild the project and download to the product, it works as a mono audio device.But the sound it recorded is not right. I know that it is because the sound data is not right.

How to make it right?

Thanks.
