In cases where the limit is not reached this is unlikely to make any
difference. In cases where the limit is reached, it is obviously a very
big improvement.

Title:
  Backport limit increase for pulseaudio number of streams

Status in pulseaudio package in Ubuntu:
  New

Bug description:
  Pulseaudio 4.0 has a limit of 32 simultaneous streams, which may be
  multiple instances of music/video players or multiple browser tabs. If
  this limit is reached it is not obvious what is going on, there may be
  a wrongly-worded error message like 'Init failed: Too large', it may
  cause significant problems, or the unexpected resumption of audio
  hours or days later without it being obvious where it is coming from,
  and in one case seemed to mess up alsa requiring a reboot.

  This limit is unnecessary and has already been fixed in pulseaudio
  5.0. Please backport this change, which is only a single number, to
  Ubuntu 14.04 LTS, so that these failures no longer occur.

  The proposed single number change:
  http://pulseaudio-discuss.freedesktop.narkive.com/3jsDewHK/patch-sink-increase-max-sink-inputs-per-sink
  A recent version of the file including the change:
  https://github.com/otcshare/pulseaudio/commits/master/src/pulsecore/sink.h
  The pulseaudio 5.0 release notes saying the change was included there:
  http://www.freedesktop.org/wiki/Software/PulseAudio/Notes/5.0/
  "sink: Increase max sink inputs per sink"

  The change is in pulsecore/sink.h
  -#define PA_MAX_INPUTS_PER_SINK 32
  +#define PA_MAX_INPUTS_PER_SINK 256
