[LAU] How to play multiple bluetooth (BT 4.0) audio receiver ?

[Ralf Mardorf]

You want to send digital audio signals to at least two receivers. The
two audio signals belong to the same sound source e.g. left and right
channel or just one channel, but still send to 2 receivers. Assumed you
should solve the issue of your request, then how would you sync the
audio signal of the two receivers?
