[meta-xilinx] c920 camera no sound meta-topic poky dora branch

[Edward Vidal]

 hello all,
With meta-topic and poky dora branch I was able to create a version for
zedboard that supports
gsl, gnuplot, v4l-utils, git, jasper, fluidsynth, liba52, boost,
qt-mobility-x11, libmad, and java.
This build with a modified defconfig for 3.12.0 kernel has the modules for
the C920 camera.

Still I do not have sound.

I have a my-image created with meta-topic can you tell me how you were able
to get sound was it with my-image meta-zynq or meta-topic?

Any and all help is appreciated.
Thanks
