Yes, if I leave out the sync=false part on the jackaudiosink module,
it only plays half a second and then stops, just sitting there,
outputting no audio.

I did however try this: 

nice --15 gst-launch filesrc location=audiodump.wav ! decodebin ! audioconvert  ! audioresample ! jackaudiosink sync=false

Now it plays the audio fine, but using very much CPU. The audio is
playing perfectly. There seems to be some scheduling problems here. Is
gst-launch not requesting proper scheduling priorities?.
