I think ROON has volume control. I see it in the Audio-->device setup. select DSP Volume. Then a volume control will appear on the device in ROON.
How to set up volume control on a DAC without a preamp
I am creating my system and trying to decide on a DAC. I don't have a preamp at this time and the preamps I am looking at are quite expensive. Several DAC's that i'm looking at doesn't have volume control either. Is it possible to set up volume control in ROON or HQ Player until I can get the money together for the preamp?
