"rssyes" is a great very simple service which transforms youtube videos to the standard audio-only RSS feed, which will work in any flexible podcast app (e.g. AntennaPod)
https://rssyes.com/

As an advantage - it stores audios -> it will always work. Unfortunately, newpipe or freetube are less predictable because of google's captchas etc.
