alsa support in new android-beagle build

Hi,

I downloaded new build, where it does not have alsa support.

Applying alsa support externally as mentioned in old wiki in lab.emlinux page is advised or not.

I went through boardconfig.mk, BOARD_USES_TI_CAMERAHAL what does it refer to, where it can be found in the source.

when alsa will be integrated in to the new build…

Thanks and Regards,
