I'd be willing to bet it will be near impossible to play gapless with sync.
The players are resynced to teh start of the track at the beginning of every
track.
Unless your network lag is exactly matched among players, there will be a
slight gap while each player waits for all players to be ready to start. If
all you want is gapless and in order, make the album into ONE track.
However, over the course of a 40 minute WAV, its likely that sync will have
some drift.

Thanks for this but I figured that as a cdimage, it would have helped as it
is one big long WAV file....was I wrong?

If I was it would be nice if there were a way to manage the buffers when
sync'd by playing with the streaming rates (or buffer play out rates like I
guess the pitch control does) rather than an a 'hard' resync. Whilst perhaps
not being best for audio quality this would be unnoticable for my party
purposes just fine..

As a full cdimage, with a cue...the server still thinks of each part of the
image as a track when it comes to sync, I believe. you can confirm this by
playing with just one player. If you get proper gapless with one player, and
no t when you have synced players then I would expect the above to be the
explanation.

How about trying this for a test:

Unsync all players.
Load the same playlist to all players, or the same Wav w/ CUE.
Start playback of all players as near to the same time as possible.

playing with playback rates to sync on the fly is probably too ambitious to
expect in any short timeframe.

of course, my feelings have always been that if my party guests are complaining
about tiny gaps, they arent' drinking neary enough! And for those who still
complain, I've got special music put aside that they can REALLY compain about
:)
