Question

Hello,

I am using youtube-dl on Windows, version 2020.03.24, and want to downlload a youtube-video, but only for low resolution videos I am able to get both autdio and video in one file. As you see in the example below, for highres-video, I can get the video, but only without audio. Why? I would like to get a high resolution file with video.

If I watch the same video on YT directly, I get high res video with audio.

Details see below, please feel free to ask if you need further details, thank you!
