Hi,

  On the iMX53, the sound chip sgtl5000 seems to get SDMA channel 0, but
this code in drivers/dma/imx-sdma.c:

	/* not interested in channel 0 interrupts */
	if (sdmac->channel == 0)
		return;

 causes the DMA to be ignored.  If I comment out the above, I still get no
sound...

  Anyone have any ideas?

  Thanks much for any help.

  Rick
