Affected Android/Custom ROM version

Android 13

Affected device model

Samsung Galaxy A34

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.

Just noticed that this bug occurs also the other way around: Videos with german original sound get english voice over when in Background. Example: https://media.ccc.de/v/b3163149-505e-497e-9c75-7cb233b59fcd
