Could you upload some sample flac files please? It could be that the flac files
themselves were encoded with gaps in them. Checking with Audacity might help.

Title:
  Gapless playback doesn't work

Status in “banshee” package in Ubuntu:
  Incomplete

Bug description:
  In Ubuntu 11.10, Banshee doesn't support gapless playback very well.
  It has an option in the preferences that claims to enable the feature,
  but it simply doesn't.

  With AAC and MP3, this is due to a format limitation. In those
  formats, the frame length is fixed, and so the last frame has some
  silence at the end, causing a slight gap. Several encoders, like LAME
  and Nero AAC, have implemented a tag that stores the correct track
  length in milliseconds. However, Banshee ignores this metadata,
  introducing the small gap at the end of each track.

  With FLAC, this shouldn't be an issue. However, there's an even larger
  and more noticeable gap between FLAC songs.

  Steps to reproduce:
  1. Cue two or more gapless songs, such as those on side B of Abbey Road by The Beatles.
  2. Play both songs in the correct order.
  3. Observe the gap.

  This bug was already marked as fixed in this Launchpad around 2006,
  but it's clearly not.
