Hi All,

Beaglebone  AM335x McASP0 is interfaced with AIC34 evaluation board. Successfully able to register two codec, create two nodes pcmC0D0p & pcmC0D1p and played song by opening specfic node using aplay.

During the codec registration I am getting the following error message while adding the widgets.
