Blender video editor: Sound fading discontinuities

I am trying to fade out/in sound strips using volume key frames. It seams the volume is stepped each video frame which leads to audible noise. Someone already made a ticket in 2010: https://developer.blender.org/T24194 . I can’t imagine this is not fixed yet and I think there must be some configuration option which I am not aware of.
If this is not the case the volume fading feature is completely useless and i have to edit each sound strip in an other application.

If someone could please tell me what is the status on this issue.

Thanks

I’ve never had a problem with volume key frames for fades. It sounds like your fcurves are being interpolated incorrectly. Open the volume keyframes in the graph editor and play with the interpolation settings. If it isn’t this, I’ve got no clue. Good luck!
