MUsicbee Volumio

Greetings, could someone help me with how I should configure the Musicbee player, to be able to play music, from a PC, on a Raspberry pi 4, with DAC Hifiberry digi, with Volumio 3, installed. Thank you

You would need to install Upnp / DLNA plugin (the plugin is no longer actively developed) and configure it to run as controller. You should then be able to see Volumio listed in output, provided both are in same network.

I could tell myself how I should configure it to run as a controller. Thank you

Perhaps you could tell yourself how too.
But you could always ask here.
