Title:
  Simultaneous BT headphones and mouse connection cause audio lag

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  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.
