No data transfer over DMA FIFO

$

Hello All,

 

I'm running LabView 2013 and have updated all the drivers and versions on my local computer and also on the Single Board RIO 9636 I am using. My goal is to measure 4 analogue inputs corresponding to four different microphones and then output each individual signal as a waveform. I am attempting this using 4 DMA FIFO's.

 

The problem I'm running into is that I am not able to read data in the RT Microprocesssor VI when using the 4 FIFO.Read methods. I am rather new to labVIEW and programming using an FPGA. I have enclosed both block diagrams for informational purposes. I thank you all in advanced for any assistance you may be able to provide.
