Roon Rock 'Missing Codecs' despite putting ffmpeg in /Data/Codecs directory

[BlackJack]

Hi @Michael_Wilson1 and welcome to the forum.

Make sure the executable bit is also set. Se the discussion in this thread:

Unable to play m4a, mp3

There are a few situations where ROCK will attempt to chmod the ffmpeg binary on its own if it is wrong. I bet one of those conditions triggered. I’ve seen Linux smb mounts get the files over to ROCK w/o the execute bit set, even though it says its 777 on your Linux side.
