Audio-Seeker sync problem when repeatedly nudging an audio clip backwards

[Jean-Francois Arseneau]

When you repeatedly pull the audio clip back, the audio goes out of sync with the seeker bar

Steps to Reproduce:
1. Start Jokosher and open a project
2. Add an instrument and import an audio file
3. Make sure the audio file has enough space on its left side for it be nudged that way
4. Press play
5. When seeker is over the audio clip, quickly nudge the audio clip to the left at least twice
6. Let the seeker play past the audio clip's length and the audio should still be playing even when the seeker is in the grey

Expected Result:
For the audio to always match the seeker's location

System Information,
Software:
Ubuntu Edgy (6.10)
Recent build of GStreamer from CVS
Jokosher r1120

Hardware:
Asus A7N8X Deluxe
2 soundcards, onboard NVidia nForce2 soundcard (main one), Ensoniq AudioPCI (secondary)

I think I have a similar problem. I was going to file this as a "big" bug report on audio splitting but there are quite a few "nearerly-duplicates" so I comment here.

To explain the shot: I was going to split the imported song right before the voice starts. Playing the song from the start the voice will begin on the red mark in the first graphic (you see the wave go up here). But, if you set the seeker to position a) the voice will be out of sync and start about where I marked b)

Also, look at the third graphic. When playing this from the start the audio will stop on the light-blue mark even though the wave indicates that there is still audio. The audio will then continue to play on the second light-blue mark although the second part of the file begins a second or so later.

Btw tested today with latest Jokosher/Gstreamer/Gnolin all from CVS/SVN

When I try to reproduce, just moving the event at all will stop playback, which in itself is a bug in my mind.
