Title:
  Simultaneous audio-out has a slight delay [per-card interface].

Status in The Linux Lowlatency Kernel:
  Unknown
Status in PulseAudio sound server:
  Unknown
Status in paprefs package in Ubuntu:
  Confirmed

Bug description:
  When either listening to music, watching a movie, viewing Youtube on
  Chrome, using *any* application, if I have Simultaneous Output
  enabled, the resulting audio output is generally delayed on one sound
  card from the other, and I cannot seem to find a viable way to fix
  this.

  All speakers are equally far from the user, so the speed of sound
  travelling has nothing to do with this to my best estimations.

  What could it be that is causing these issues?
