Volume control with bit perfect on?

[altec]

Hi all, I just installed UAPP and trying it out connected to a car DSP. I have managed to fiddle around and get it to work with volume control but with bit perfect off. Can it work with bit perfect on?

If you have a USB DAC which features hardware volume control, then that is what the default behavior is and should work with bit-perfect turned on.
