I'm making no progress on this, in spite of having spent several hours investigating :-(

Slight correction to the symptoms - once booted, the device sends no packets - it is the Audio Manager software that is trying to connect on udp 18678.

Telnetting to port 5000 gets rather random results - sometimes the chars echo, sometimes not, and I can't get the simplest of commands (e.g. ls or pwd) to run. This leads me to believe that slimrio simply isn't working properly, unless I am doing something wrong? Has anyone used the port 5000 interface? Do you need to do anything special to make it work?

Cheers

Tim

PS I have tested it using the original Rio software - works perfectly
