This is general issue for all Disneydags episodes that I have tried with, not just episode 21.

For now, try -f 'bestvideo+bestaudio[format_id!*=lb]/best'.

For now, try -f 'bestvideo+bestaudio[format_id!*=1b]/best'.

Thanks for the tip!

With single quotes I got ERROR: requested format not available, but with double quotes, changing 1b to lb, switching to ffmpeg 3.4.2, and using ffmpeg as downloader (see #30208), it actually works:

>youtube-dl --hls-prefer-ffmpeg -f "bestvideo+bestaudio[format_id!*=lb]/best" https://www.svtplay.se/video/33694750/disneydags/disneydags-sasong-1-avsnitt-23

Ah, lb = low bandwidth? That could make sense (l vs 1).

'Single quotes' for POSIX, "double quotes" for Windows.

Also, you could sort the audio formats like this (hls_best/hls_less_good/bestaudio) (eg, fill in the best, less_good) instead of just picking the best audio format that's not -lb-.
