Comment (by jb_alvarado):

 I think I have now the "workaround". The correct numbers of samples per
 frame needs to be calculated. For example for a 25 FPS Video: `192000 / 25
 = 7680`, this can be used in '''asetnsamples=7680''', or in combination
 with '''aresample=48000''': `48000 / 25 = 1920` ->
 '''asetnsamples=1920'''.

 Is a bit confusing, because there is not always a video line and it also
 looks like that higher numbers like '''8192''' or also working...
