Record audio from Sequencer?

Hello I want to record audio with attenuation from the sequencer to a wav file.
The audio is bound to an animated object and i am looking for doppler effect and left right distribution.
Somehow it works in the sequencer and also when playing or simulating, but when rendering the wav is empty.
I am on 5.3 and use 3 different approaches:

  1. Audio Track in Sequencer
  2. Audo as part of the Blueprint Component
  3. Audio as Event Graph “Spawn Sound Attached” with custom event triggered from the Sequencer

All works but no wav recording -.-
