[yocto] [meta-raspberrypi] RaspberryPi2 - no audio?

[Gary Thomas]

I just built Poky/Yocto for the RaspberryPi2, straight out
of the box using this configuration:

Build Configuration:
BB_VERSION        = "1.25.0"
BUILD_SYS         = "i686-linux"
NATIVELSBSTRING   = "Fedora-13"
TARGET_SYS        = "arm-amltd-linux-gnueabi"
MACHINE           = "raspberrypi2"
DISTRO            = "amltd"
DISTRO_VERSION    = "1.7+snapshot-20150321"
TUNE_FEATURES     = "arm armv7a vfp thumb neon callconvention-hard vfpv4 cortexa7"
TARGET_FPU        = "vfp-vfpv4-neon"
meta              = "master:12b6cf0f2212519b14333519746174a5b941f7bf"
meta-amltd        = "cutting-edge:d9350ea229c04d64111f38e638f372a1bac87be0"
meta-raspberrypi  = "master:b896a7da70dd7a16ba7ffd664f7747cb37e1d142"

All seemed to go OK, but when I try to play audio, there are
no sound cards found.  Is there some configuration I need?
Once I get it going, how can I select between the internal
(phono) audio and HDMI?

Note: I had this working just fine on my RaspberryPi (model B)

Thanks
