No Waveforms

Hi there,
Resolve will not show me waveforms(again...). What i tried:
- Waiting for it to show up
- Toggle timeline view options
- Generate optimized media
- Switch on smart render Cach
- Delete CachClip
- New project
The sound is a 45min Wave recorded with a Zoom H4n, Stereo.
But even the in-camera-sound from the bmpcc 4k (braw) does not have any waveform. But the .mov files from a Panasonic GH5s do have a waveform! Please help, i dont understand this.
