Can't play any Live Radio station

Thanks for the prompt reply.

I’ve been doing some more digging around and testing and I’ve worked out what is going on.

I’ve got roon running under a non-root user by using effectively the same steps as documented here:

Running roon on Linux Ubuntu 18.04 as a user (not as root)

When installing the Roon Server on a linux system, it is recommended to run the application as root in order to give access to all the necessary system ressources that roon needs to function properly. Perhaps this is an acceptable work-around on a Rasberry Pi, or other small computers dedicated exclusively to roon. But in general, this is a somewhat unorthodox practice and may create significant security risks, especially if the roon core is running along other services (openvpn, file server, ss…

This user has a home directory outside of the /home folder.

The version of ffmpeg that was installed as a ‘snap’ as this installed a much newer version of ffmpeg that the one the comes in the default apt repository.

Unfortunately tools installed via ‘snap’ do not function correctly for users that do not have a home directory under /home (see Bug #1620771 “when /home is somewhere else, snaps don't work” : Bugs : snapd) and I confirmed this by trying to run ffmpeg as the same user roon runs as.

This means that while a working version of ffmpeg was installed whenever it was invoked by the roon process it terminated immediately with an error, hence the error with no stream being read by roon.
