Is it possible to add a clip to the timeline with a split audio automatically?

Uummm... Using the search for you, I have found this thread opened by... well - surprise. ;-)
http://www.kdenlive.org/forum/how-split-video-and-audio-automatically-when-dragging-timeline

I guess the feature is not available...

In my version of Kdenlive, at the bottom just right of the timeline zoom is an icon that says, split audio and video automatically. Also, it can be done via settings - configure Kdenlive - timeline.

Ups... I do not use it and manually split two or three times a year... Sorry...

To tell you the truth, nor do I :)

It is available in the kdenlive-setup
