Comment 86 for bug 644644

The Pulseaudio package seems to be causing the issue. In Banshee it plays a song X, loads the next X+1, skips it then loads and plays X+2

debug output from Banshee:

[1 Debug 01:03:44.616] Track Terry Pratchett - Feet of Clay 067-117 (on Feet of Clay) <00:05:09.2190000> [file:///home/david/Musik/Terry%20Pratchett/Feet%20of%20Clay/67.%20Feet%20of%20Clay%20067-117.mp3] had playtime of 307628 msec (307sec), duration 309219 msec, queued: False

Now clearly the last "had playtime" is a lie as the data shows it ran for around a second not 308 seconds.

Banshee's GStreamer shim:

Also in this case gapless playback is enabled, however this does not appear to have an impact on the issue.
