[Bug 1258882] [NEW] Simultaneous BT headphones and mouse connection cause audio lag
Public bug reported:
If bluetooth mouse connected after headphones (external BT audio
speaker), sound getting laggy (sometimes interrupts and not in sync with
video). If connection order is reverse (mouse, than audio) problem is
much lesser visible (rare glitches and almost fine sync in video), but
still annoying.
