Could you not try to output the same audio frame a couple of times according to pseudo algo:

For each audio frame:

if (audioFrameEnergy < silenceThreshold) // Would help make it less noticable
{
if (video lags audio by x ms)
{
run last audio frame again;
}

        if (audio lags video by x ms)
        {
                drop an audio frame;
        }
}

That way audio should keep up, but I don't know if that's good enough for you.

Where by "Time Stretching" technic was supposed to be the solution.
But no such Logic or the Algo.. or the Source Code that explains how it can
be executed was found on the net till yet.

Any help towards any of these areas will be gr8 help to me..
