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

Are you providing the mx53 sdma firmware?
