Your system appears to be mixing and matching the standard ffmpeg
packages from Ubuntu 16.04 (version 7:2.8.11-0ubuntu0.16.04.1) and
nonstandard ones from PPAs.
Please purge all PPAs from your system and retest:
1. sudo apt install ppa-purge
2. sudo ppa-purge .... (on all the PPAs you are using)
3. Retest and provide new output from 'dpkg -l | grep libav > libav.txt'

Title:
No audio on vlc or videos sound or video files
Status in pulseaudio package in Ubuntu:
Incomplete
Bug description:
Up until a few weeks ago there was no problem with playing sound from mp3
files. I have a pair of usb speakers. Audio plays Ok on them for video clips
using Chrome (e.g. from BBC website). Using vlc 2.2.2 (from Ubuntu repos),
neither a CD nor DVD (video is Ok) nor mp3 file plays audio. mp3 files play Ok
using Rhythmbox. I've also tried vlc 3.0 with no success.
Interestingly, the standard Videos app (Totem?) also doesn't play sound on
these speakers either of an mp4 file (downloaded from YouTube, though it plays
Ok on YouTube website using Chrome) or a DVD. Clemenetine plays mp3 files Ok. I
first reported this as bug 1752267 as I thought that the problem was with vlc.
On that bug, it was suggested that the problem is with Pulseaudio.
Just now, I've tried to play sound through my monitor's built in speakers
connected by hdmi (though the monitor displays Ok) with no success even though
the built-in speakers play sound using pavucontrol when testing is invoked.
