Can't reliably sync animation with sound using krita's in program audio

tested with an audio file counting down 10 to 1 
Marked every 24th frame 10,9,8,7,6,5,4,3,2,1 repeated for 60 sec

around the 120 frame audio was starting to delay studder

Audio reached the end of the loop "3,2,1-10" between 312th and 336th frame 
14 second of animation for what should be 10 seconds of in program audio.

Rendering out the animation resulted in 60 sec and the correct timing of audio and frames.
