Audio and Wifi disabled for Beagle board Xm

Hi ,

 I am using Android ICS source from below link.

http://processors.wiki.ti.com/index.php/TI-Android-ICS-4.0.3-DevKit-3.0.0_DevelopersGuide

I have built the source code and ported images on BB-Xm.

Following features are not enable in  my build.

1. Audio is disable. 

   When I connect BB-Xm board to TV using HDMI, audio is not present. It is disables.

2. Wifi is disabled.

Could you please suggest to enable the Audo and Wifi on Beagle Board.

Thanks in advance,

Rajesh.
