I'm getting some feedback from Moode users that are configuring the DAC+ Pro and are wondering about whether the 0dB gain point that is displayed in alsamixer is correct. We are seeing 40 on the slider scale = 0dB. This is for both DAC+ and DAC+ Pro.
Moode running on Raspbian, kernel 4.1.10
DAC+Pro and DAC+ ALSA 0dB level
