Title:
  Slow Audio Playback through DisplayPort monitor

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Dell XPS 13 (9343) hooked up to a Dell U2515H Monitor running
  16.04 (clean install around beta) and connected to the monitor via
  3.5mm stereo out I have a pair of Logitech speakers. When I hotplug
  the monitor to my laptop and try to play audio through "HDMI" the
  audio plays at what seems to be half speed.

  The source of the audio does not matter (local audio/video, internet
  audio/video stream etc) but if the laptop is rebooted with the monitor
  connected, the problem does not manifest. Playing audio through the
  internet laptop speakers with any setup seems to work fine, as does
  playing audio through the laptop headphone jack.
