You can check if pulseaudio is running:
ps -C pulseaudio

You need vlc-plugin-pulse if you want to use pulseaudio as sound output.

Just add "vlc-plugin-pulse=2.0.4-1" to your aptitude command.

Are you really using version 2.0.3-2, because VLC claims to be in
version 2.0.1?

The asynchronism between the audio and video is probably the reason for
your missing audio after unpause. Upstream fixes some synchronization
issues in 2.0.4 and after that. So I recommend to test 2.0.4. If 2.0.4
is still affected, I suggest to test their latest commit from their
stable git branch [1]. If this version is still affected, I recommend to
report a bug upstream.
