Hi Forest,

i don't know how this is done on pandaboard since i have none, but on a 
tegra2 based board there is a second audio device. maybe this is done 
similar with the omap drivers. then you command would look something 
like this:

 > gst-launch playbin2 uri="myfile" video-sink="pvrvideosink" 
audio-sink="alsasink device=hw:1,0"

you should be able to see if there is a hdmi output by looking into:

cat /proc/asound/devices
cat /proc/asound/cards
