Audio scrub aka scratch ??

Hi all,
Have been fooling around with some Linux NLE's the last few days and have been impressed with KdenLive and see a great potential.
It is especially nice to have subclips.

I am using the .6.0 wit Kubuntu 8.04. The sound works fine in normal play time but there is no sound for scrubbing.

I gather this is a the state of Kden live ? I saw the feature request below in the wiki

"Support of jack sound system for real-time sound editing. (and scatching while searching a certain point e.g. bassdrum)"

Does any one have sound working for scrub / search ?? If so how do you do it ??
