OBS with audio/video grabber for videorecorder, no audio output

[Seaman]

I'm just a beginner with OBS to convert VHS-videos to digital files on my computer.
PC with NVIDIA-card.
Gembird audio/video grabber
The video output is good, but no audio output.
I see problems in the log-file, but what to do to get audio output?
