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 -Pierre
