Title:
  OpenAL Software Silent/Freezes

Status in openal-soft package in Ubuntu:
  New
Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  Following an update I made this week to the system, I have attempted
  to play a number of games, including "X Rebirth" from gog.com,
  "Minecraft," downloaded from Mojang.  In those games making use of the
  OpenAL library, no sound is coming through PulseAudio; there is a
  stream listed in Pulse, but there is no sound, and the meter does not
  indicate that PulseAudio is even receiving any audio.  I am also
  noticing the problem in Blender, but in this case, the issue seems to
  cause the VSE to stick to the frame it's at when set to "A/V Sync"

  To make matters worse, once the stream shows in "pavucontrol," the
  program won't end.  If the audio is integral to the software, such as
  the case of Blender, the software itself will freeze when I attempt to
  close it; I will have to kill the program to make it shut down
  completely.  Other programs that use a sound server with OpenAL seem
  to close, but the stream is still showing in pavucontrol, and the
  process is still shown as running in "ps x".  Killing the frozen app
  makes it go away; and so far, the normal kill command will work;
  there's no need to "-9" it.

  Even openal-info freezes, after displaying the following:

  -------------------

  This problem persisted, even following a clean installation with no
  PPAs installed.  I'm assuming the problem is in OpenAL, because
  programs not making use of that library (YouTube, VLC, etc.) don't
  seem to have the problem.  The update that seemed to be the breaking
  point was an update to kernel 4.2.0-34 (I no longer have the original
  system, thinking a full restore would fix things), so there might be
  something in the new kernel that's interfering with OpenAL.
