This is the response from the Audacious developer concerning the trackid requirement in MPRIS2:

-------- Original Message -------- 
Hi Ted,

I am aware of this "bug", but it is unfortunately a "wontfix", or more
precisely a "cantfix".

The thing is, MPRIS v2 was written apparently without much consideration
for playlist-based players like Audacious.  Unlike Amarok, Rhythmbox,
Banshee, etc., where there is a database holding all the tracks, in
Audacious, a song is identified only by its position in the playlist,
which can change without warning.  Hence, we can't provide reliable
track identifiers.

>From what you said, I gather that cairo-dock is waiting until "trackid"
changes to check for changes in the metadata.  That's not a good idea
anyway, since metadata can change even within the same track.  (Think of
internet streams, or of the case where a user edits the tag on a file
while it is playing.)  MPRIS v2 metadata uses the D-Bus properties
system, so a more natural and more reliable way to watch for metadata
changes is to connect to the "PropertiesChanged" signal.

I hope this helps.

Title:
  MPRIS2: the trackID is not updated

Status in Cairo-Dock: Plug-ins:
  Invalid
Status in “audacious” package in Ubuntu:
  New

Bug description:
  I've been working with the source trying to get a feel for the
  project. I "partially" fixed one of my issues, the music player not
  updating the cover when songs change. I got the icon to update
  whenever a new cover is not found, but still haven't gotten the tool
  tip text to update.

  static gboolean _on_got_cover (CDSharedMemory *pSharedMemory)
  {
  	CD_APPLET_ENTER;
  	if (pSharedMemory->bSuccess)
  	{
   		...
   	}
    else 
  // I added the 3 following lines
    {
   		cd_musicplayer_apply_status_surface (myData.iPlayingStatus);
    }
  ...
  }
