I have an embedded board that running with Dragon ball, and have a sound
   IC on it. However when playing mp3, it always print out this error
Sound: DMA (output) timed out - IRQ/DRQ config error?
And I see it keep on runnig the close routine of the dsp driver.

And some times it print out this error for many times
Sound: Error. Audio interrupt (0) after freeing buffers.

How to fix this bug?
Any idea?
