Steps to Reproduce

• Teleport to a region which has a large number of sound sources, for example http://maps.secondlife.com/secondlife/Glint/210/21/22

• Wander around the region and periodically open/close some floaters or otherwise trigger some UI sounds.

  Observed Behaviour

• After a time, you will hear the inworld audio sources start to repeat and stutter.

• When you open floaters, for example Inventory or the main map, you will hear the open & close floater UI sounds repeating quickly multiple times.

• If you use the Glint region, you should see this bug reproduce within 30 minutes of wandering around on the region.

• Demo video made on Second Life 3.7.28 (300918) Apr 14 2015 17:06:20 (Second Life Release) can be seen here: https://www.youtube.com/watch?v=_sJugMwvdMo&feature=youtu.be

• See SecondLife.log attached.

  Expected Behaviour

  The viewer should be able to handle a large number of sound sources better.

  This is not a new bug, it happened when the viewer was using Fmod instead of FmodEx.
  This is the same bug as VWR-28101 but I cannot find an issue for this that was ever imported, so refiling.

  Worth a retest when the viewer is updated to Fmod Studio (OPEN-279)
