For one, pulseaudio is not a part of Lubuntu. That shouldn't cause your
problem, but it may complicate things. Also, I would cause this a
support issue. Please check out
https://wiki.ubuntu.com/DebuggingSoundProblems and see if you can't get
to the bottom of this.

Title:
  No sound output lubuntu 14.04

Status in “pulseaudio” package in Ubuntu:
  Invalid

Bug description:
  All automatic updates have been installed on my system (bug reporter
  couldn't find an update trail, so that may be an issue, too).

  Recently, in the middle of a session, my sound output ceased. Just
  before it happened I had made minor changes to the Default
  Applications using the GUI - those changes were only to replace
  Abiword and Gnumeric with their Libreoffice equivalents for
  spreadsheets and word processor documents.

  Launching "Volume Control" settings, the Alsamixer display had no
  indicators for controls listed under 'playback' (f3). Instead, there
  is just an item labelled <S/PDIF> with '00' in a box above it and this
  does not respond to numeral or arrow keys.

  I have tried reinstalling Pulseaudio. This hasn't helped. I have
  installed pavucontrol. Now, during playback of video and sound files,
  when I view pavucontrol the blue levels indicator for my sound cards
  is moving as if there is a signal, but there is still no sound.  I
  have tried plugging in other speakers to confirm that it's not my
  speakers at fault. I have also tried adjusting the level under the
  'output' tab of pavucontrol, but this has not helped, either.

  An unresolved thread on Ubuntuforums.org suggests that one Ubuntu user
  has had this problem on x64 architecture just after intalling version
  3.13.0-37 of the Linux kernel. I have the same Kernel version. Another
  user has had their sound disappear, then reappear after putting their
  laptop in sleepmode overnight. Again, same kernel version, but desktop
  environment unspecified.
