I have this wrapper for the omxplayer - note the
line with adev - I put local there and the
3.5 mm audio port sends sound.

However putting 'hdmi' or 'both' there, as the
man page describes, doesn't get the HDMI
(audio) going.

plo () {
    local file=$1

    if [[ ! -f $file ]]; then
        no-file-msg $file
        return
    fi

    local keys=~/public_html/conf/.omx-keys

    local vol_mod=0
    sudo omxplayer --align center     \
                   --blank            \
                   --key-config $keys \
                   --loop             \
                   --font-size 35     \
                   --vol $vol_mod     \
                   --adev local       \
                   $file > /dev/null
}

Also, I wrote this function to test the sound:

test-sound () {
    sudo modprobe snd_bcm2835
    for output in 0..2; do
        sudo amixer -c 0 cset numid=3 $output
        sudo aplay /usr/share/sounds/alsa/Front_Center.wav
    done
    /opt/vc/src/hello_pi/hello_audio/hello_audio.bin   # 3.5 mm
    /opt/vc/src/hello_pi/hello_audio/hello_audio.bin 1 # HDMI
}

Well, at this point, it confirms the state...
