MP3's not playing on Roon

[agent_kith]

I dont seem to be able to play mp3's using Roon server on Snakeoil OS. Am sure I used to be able to but dont play them often so not sure when things changed.
I asked at Roon forums  here but so far they think "This seems to indicate a version conflict between ffmpeg and libraries on your system it depends on"

This is not device dependant

Hmm.. That could be a reason as Snakeoil is using a custom built ffmpeg library...

Can you help and run the following commands, and show me the output of each one?

Code:

ls /usr/local/lib -l

dpkg -s ffmpeg
