I have OrangePi Zero2 and Behringer U-phoria UM2 USB audio interface lying around. I’m thinking to use them to build a Volumio setup that connects to an analog HIFI using the USB Interface.
The goal of this setup is to play lossless audio files (.flac)
Not many will have this combination of hardware components, but there is no obvious reason why this should NOT work. Linux has a standard driver for usb audio and this is enabled in all Volumio images.devices.
Unless the Behringer misbehaves badly (which is verly unlikely), you should be OK.
