Do you have the appropriate set_GPIO_IRQ_edge() in your machine specific support code for the GPIO pin corresponding to interrupt 43? > If I ignore the warning message audio playback works as expected.

I'd have thought so. _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
