Normal mode description:
Start playing the audio file (using DMA).
Using this mode, the application can run other tasks in parallel since
the DMA is handling the Audio Transfer instead of the CPU.
The only task remaining for the CPU will be the management of the DMA
Transfer Complete interrupt or the Half Transfer Complete interrupt in
order to load again the buffer and to calculate the remaining data.
Circular mode description:
Start playing the file from a circular buffer, once the DMA is enabled it
always run. User has to fill periodically the buffer with the audio data
using Transfer complete and/or half transfer complete interrupts callbacks
(EVAL_AUDIO_TransferComplete_CallBack() or EVAL_AUDIO_HalfTransfer_CallBack()...
In this case the audio data file is smaller than the DMA max buffer
size 65535 so there is no need to load buffer continuously or manage the
transfer complete or Half transfer interrupts callbacks. */
