I don’t have a pre-amp in my chain so I use Software Volume Control.
When I play DSD files over DoP to my Northsrar DAC that supports up to DSD128, the volume is not adjustable on iOS App and plays at 100% level (though I set the volume limit to about 40%). So I have to use DSD to PCM option.
I have the same issue on both Audirvana 3.5 and Studio.
Has anyone else noticed this? And is there a fix?
