Gapless playback

[Cebolla]

Yes, it's possible that Naim haven't taken gapless support into account when the user manipulates the tracks in the playlist while the current track is still playing. So cancel the old cued next track (if set) on the NDX and cue the new next track, every time the next track in the playlist changes while the current track is still playing.

Note, this only needs to be done for those players that are instructed by their controller apps to cue the next track for gapless just after the current track has started playing. Some controllers are designed to only send the cue next track instruction to the player just before the current track has finished playing, to avoid this issue.

The BubbleUPnP (Android) app is an example of a standard UPnP controller that sends 'early/at current track start' cue next track instructions;
mConnect Player is an example of a standard UPnP controller that sends 'late/at current track end' cue next track instructions.
