Trying to make my frigate record/play sound from camera

Hello everyone…
I have most of my issues with frigate sorted out and want to go afte the cherry on the cake now…
And that is sound.
I saw many examples on how people do it, but so far i wasnt able to have my recording, or my preview talk to me.
I am using Sv3c onvif enabled wifi and lan cams and they all have sound via direct web and vlc stream.
I have them all like this:

go2rtc:
  streams:
    # stream which supports video & aac audio. This is only supported for rtsp streams, http must use ffmpeg
    rtsp_driveway_cam:
      - rtsp://usr:[email protected]/11

in go2rtc.
And in the camera section i do like this:

cameras:

  driveway_cam:
    ffmpeg:
      inputs:
        # High Resolution Stream
        - path: rtsp://127.0.0.1:8554/rtsp_driveway_cam
          roles:
            - audio
            - record
        # Low Resolution Stream
        - path: rtsp://127.0.0.1:8554/rtsp_driveway_cam_sub
          roles:
            - detect
      output_args:
        record: preset-record-generic-audio-aac

as i found in several examples…
But so far no dice.
Than i saw in the documentation that reolink’s need extra flags:

path: rtsp://127.0.0.1:8554/your_reolink_camera_via_nvr?video=copy&audio=aac

But did not help
Any hint available how to find out what i am missing?
Thx in advance
