Audio Playback and Record, DMA from RAM

When executing the audio clip from flash[const defined location as in the example project] the audio file plays fine, but if I remove the "const" as to allocate ram for the audio clip, I get only a small block of white noise...I'd figure that given the DMA configured as memory-to-peripheral there to be no issue...looking at the output with a logic analyzer, the bytes appear to be the same in both conditions[audio clip executed from flash, and when from ram]...any suggestions as to what could be the subtle difference causing the problem would be much appreciated...
