OK. A little progress. The rt kernel would not work on my system, i am investigating, so i installed the linux-ck kernel. In the kdenlive preferences i can switch the audio system which is used for playback. When i use pulseaudio i get a delay in my markers of about 5-6 frames (200-240ms). When i switch to ALSA i get a delay of 2-3 frames (80-120ms). That's a little better. I will try further audio servers (e.g. OSS) to see where i may get a further improvement. Also will try to install the rt kernel... Any ideas, how i can get it right on the spot? My system latency is around 30ms (cyclictest).
