To test the loopback, what I had in mind was enabling a BT sink
(receving data from somewhere else using A2DP) and playing locally on
the speakers. That should trigger all kinds of latency issues since
the transmitter essentially pushes packets without worrying too much
about time, and the receiver has to do all the synchronization work.
Should be fairly easy to enable by modifying the
/etc/bluetooth/audio.conf, but I haven't had the time to test so far
