Brad,

Thanks the the info. Just a question or two... Are you saying that
timing information actually makes it all the way out to the headset? I
assumed it was just raw data, and the headset just tried to play it at
the appropriate speed. (the headset could then vary a bit depending on
how full the buffer was) 

Also, yes, the idea of having the latency info fed back to the source
had occurred to me as well. Is there any way at all to estimate the
delay from the headset tho? or would it just have to be a value you tune
manually? Also, do you know if gstreamer is able to do this kind of
thing now?

Thanks again,
Scott
