Background information

I am currently using Logitech Media Server and Raspberry Pi to stream music around my house.

The music is on a server running Open Media Vault, the server runs Logitech Media Server.

The Raspberry Pi computer is the client and runs Max2Play, it plugs in to some speakers via the line out port.

Looking at the Logitech Media Server interface I can see the music is playing but I am not getting any sound through my speakers.

Can you help me trouble shoot this issue?

I am not sure if I should be adjusting a setting on the Logitech Media Server software or on the Max2Play software.

Perhaps the software isn't the issue and it's something else?

Any advice or feedback is welcome.

Thanks in advance
