I’m using Ropieee with a RPi4 with USB from the RPi into a Soncoz SGD1 DAC.
I also have a Logitech Transporter that I can stream to using Roon. I use the AES/EBU input to the Soncoz DAC.
I’ve found that sending the same file to either the RPi using USB or to the transporter using AES the volume is at a much lower level with USB from the RPi. I have both devices set as fixed volume in the Roon device settings as I am controlling the volume with the Soncoz DAC.
Is there something else I can set in the Ropieee settings to adjust the volume level?
I have installed PiCoreplayer on my RPi4 in place of RoPieee. The volume from the USB input to the DAC is now the same as that from an AES/EBU source. It seems that the issue with the different volume levels between USB and AES inputs to the DAC is with Ropieee.
I have the PiCoreplayer enabled in Roon as a Squeezebox device. Fixed volume level.
Is there any other volume setting in Ropieee. I can see ‘forced volume’ but I don’t know what that is supposed to do?

Actually, it sounds to me as if this is a Roon Core thing. Depending on how it sees your endpoint, what it sees that endpoint as being.
Roon Core server > Ethernet > RoPieee > Raspberry Pi4 > USB cable to DAC.
Roon Core server > Ethernet > Logitech Transporter > AES/EBU cable to DAC.
The DAC has a digital volume control so both devices are set to fixed volume in Roon.
If I leave the volume control at the same setting on the DAC and I play the same file to setup #1 and setup #2, without changing the volume level on the DAC, the output level is much lower with the USB input from RoPieee than it is with the AES from setup #2.
If I replace setup #1 with:-
Roon Core server > Ethernet > PiCoreplayer > Rasberry Pi4 > USB cable to DAC.
Then the volume output level is the same with both this and AES input setup #2.
I hope that explains the problem a little better. The volume output from the DAC should be the same no matter what the source is.
