[Aaron <dartmetrash@xxxxxxxxx>]

I'm playing over analog headset and USB headset simultaneously, and I
experience around a 5-second delay. I have an organ with GNU/Linux
running on it (motherboard is inside the organ), and I'm trying to
record my wife singing while I'm playing organ. We need the organ sound
to come through both headsets so that it is not recorded with her
singing. A 5-second delay is prohibitive. Thanks!

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

Status in linux-lowlatency:
  Unknown
Status in PulseAudio:
  Invalid
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?
