How to get AC3 passthrough on Freescale IMX6 Yocto image ?

[Subodh Chiwate]

Hi,
I am using a SABRE-SD IMX6 Quad board.
I have built the image using instructions from freescale git for
3.10.31+. (Not using X11, instead trying with directfb ).

I have working gstreamer 0.10 and 1.0 on board and can decode audio and
playback on HDMI
using the following settings for ALSA.
https://community.freescale.com/docs/DOC-93745

But I need to pass the audio directly to HDMI for decoding.
Is pulseaudio a must for getting passthrough to work ?

Please let me know in case more information from my setup is needed.
Thanks.

Following is my board setup
