yes, I think this was on my todo list ; using STMemory_DMA_ReadByte in 
DmaSnd_FIFO_Refill() should take care of this possible problem.
DmaSnd_FIFO_Refill() is called only on every HBL, so this shouldn't have 
a noticable impact if we used STMemory_DMA_ReadByte() instead of 
directly accessing STRam[]
