Appearently, that was the problem. After installing a manual ffmpeg,  
ffplay was able to output sound, but kdenlive wasnt. inigo (mlt framework  
test player) wasnt installed, apparently, it doesnt ship with the mlt  
package. I used the kdenlive_builder script to build a local version of  
kdenlive, and there ffplay also was not capable to play the aac sound on  
my mp4 file. After I modified the build script to enable libfaac and  
libx264, it worked however. problem solved :)

Thanks for all suggestions,
