I expect this to work normally and use my YouTube-DL binary path I specified. There is a cron job setup to check for YouTube-DL updates every 15 minutes; YouTube-DL IS up to date. I compiled FFMPEG from source with all of the modules, it works, I use it very often.

Perhaps I’m missing something in TS3AudioBot?

Kind regards
