DownloadHelper Will Not Convert to MP3

I try to download a video from YouTube using the preinstalled DownloadHelper and select
Download and Convert / then select MP3 from the drop down menu / then save to desired
folder and it fails every time!

I will say when I first TRIED this OS before installing… it actually WORKED! Not after

You may need to remove the extension and re-install it.

Just tried that and it does the same thing. Conversion Failed.

Make sure you have ffmpeg installed:
sudo pacman -S ffmpeg

then make sure it’s pointing to /usr/bin/ffmpeg in the preferences > conversion tab
