[LAU] kdenlive - audio time delay

Hello All, i have a special little audio problem with kdenlive which is annoying me a lot, perhaps you can reproduce it or have an solutiuon: I like to do video cuts exactly synchronized with music song beats. So i would like to "tap in" the beats with markers before cutting to have the cut positions to snap to. That's not possible on my system, i always have about 500ms of delay when i listen to the music track and tap in the beats. So the markers are always a little to late and out of sync... Can you reproduce this? Do you have an idea? I am on Arch latest kernel, KDE, Ryzen System, tried it on Pulseaudion and Firewire external Audio Interface, Same Problem. Thanks for ideas, Daniel. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Daniel Wilhelm
