Lubuntu 14.04 no sound, can't install pulseaudio

Question

I have two PCs I've installed LUbuntu 14.04 on. On one sound is fine and pulseaudio was installed during the OS installation. On the other pulseaudio is missing, and there is no sound at all, not from audio jack nor from HDMI. When typing sudo apt-get install pulseaudio I get this error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 pulseaudio : Depends: libpulse0 (= 1:4.0-0ubuntu11) but 1:4.0-0ubuntu11.1 is to be installed
              Recommends: pulseaudio-module-x11 but it is not going to be installed
              Recommends: gstreamer0.10-pulseaudio but it is not going to be installed
              Recommends: rtkit but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Solution

You try to install the pulseaudio (1:4.0-0ubuntu11) from the trusty repositories. But you have enabled trusty-updates, therefore libpulse0 (1:4.0-0ubuntu11.1) is to be installed.

The only explanation is that you have forgotten to start the command

sudo apt-get update

After that

sudo apt-get install --reinstall pulseaudio

and to upgrade the whole system

sudo apt-get dist-upgrade

Edit your question and add the output of apt-cache policy pulseaudio

Run sudo apt-get install libpulse0=1:4.0-0ubuntu11 and then try again to install pulseaudio.

I installed pulseaudio as suggested in the last comment to my question before you posted. Sound kind of works. Then did what you said as well. Sound works, which is a progress, but stuttery and poppy if from HDMI. If from audio jack (headphones) it is OK, What have I done wrong or missing?

Sorry, but that's a new question.
