Thank you for answering quickly back.

The above command does generate a PID, I do know it's a 'server' so
it's always running.

$ ps -C pulseaudio
  PID TTY          TIME CMD
 4002 ?        00:03:36 pulseaudio

umm... this is where it is getting weird for me too.

I just purged vlc and it's other related packages from the system.

As can be seen it is suppose to purge all the configuration files.

But still when I ran the vlc -vvv I get the same output :-

$ vlc -vvv
VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)

[0x1707108] main libvlc debug: revision 2.0.1-0-gf432547

So no idea why it's not showing vlc-2.0.4 and claiming to be vlc-2.0.1

Any and all ideas welcome.

I think till the time I can't get to the bottom as to why it seems I
have vlc 2.0.1 when dpkg shows otherwise :-

$ dpkg -l vlc

Looking forward to some more answers.
