Additional information

The switch "Prefer original audio" in NewPipes "Video and Audio" Settings does not change the behaviour.

When you open the video link in a browser, there is a select for different audio traces, I did not find a corresponding switch in the newpipe app.

The system language of my phone is english, my location in germany.
