Hmmm. Way too complicated probably, but if you can actually get the device to pair and sink it as an audio device, then you can do this: mplayer -ao alsa:device=bluetooth and it may or may not require ~/.asoundrc that looks like

pcm.bluetooth {
    type bluetooth
}

I heard audio at least one time from my headphones via mplayer that way...at least before the batteries ran out. Open question: Why doesn't it just show up like a normal alsa device? Meh.
