Some urls play in video mode even when -a option is added

[AndreiBiziuk]

Issue / Suggestion

There is -a option to play playlist item in audio mode. On some urls it is working but on others not.

Not working:

yt url MFiqhfQBIJQ, '1 -a'

Status text says mp4 audio only but mpv window opens with image.

yt-dlp sees formats with audio only

-> % yt-dlp MFiqhfQBIJQ -f -
