Title:
  Sending MIDI directly out of Soundcard causes lock up

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  With my HP ENVY TouchSmart 15-j144na Notebook PC, after sending a
  number of MIDI notes out of my NI AudioKontrol 1 sound card my system
  locks up completely and needs to be hard reset.

  This problem appears to occur no matter what tool I use to send MIDI
  out of the soundcards port.

  Upon crashing:
  - screen goes black but backlight is left on.
  - Caps lock key begins to flash
