1) Be careful to pick frequencies and sample rates that the hardware is
capable of handling. That will help you immensely.

Here is a list of freq ranges for each particular daughter-board:

2) I recommend debugging at a lower level to ensure the fidelity of your
setup, like a test tone, and so on.
