I use a PC with JRiver 17 (tried to get the JPlay plugin to work - no joy). From what I gather, playing in any WASAPI / ASIO mode the slider does not work.
I control volume digitally in the Trinnov 4 channel processor

This processor sits before my PS audio DAC. I run the dac at 100. I am actually thinking of recalibrating my system, running the PS audio at 80, and doing less digital attenuation in the Trinnov.
By the way, does your DAC have remote volume control? I may decide to give it a whirl, but no remote control would be a dealbreaker.
