My setup: Raspberry 3, Raspberry Display and a HifiBerry Digi+ Pro connected via coaxial to a Oppo BDP 105. All works fine
My question: In the RoPieee web setup I see a flag āAudio USBā. Is it also posible to use a USB port from the Raspberry to connect to the USB DAC from the Oppo and is this supported from the HifiBerry Digi+ Pro? I tried this but there is no signal
RoPieee supports USB Audio to connect to USB DACās. If you use a HAT for audio out (like you do), you still can choose tho have USB Audio enabled in parallel.
It should work, but you are required to enable your USB endpoint in Roon as well. It basically means youāve got 2 zoneās running on your RoPieee: your Digi+ and USB out.
Yeah. Itās just another way of audio transport (in this case).
It just comes down to personal preference I guess.
USB of course has a little bit more capabilities (higher sample rates for example), so if youāre playing around with upsampling then it might suit you better.
