DSD play noise, dtoverlay, GPIO setting commands
#3
@George_L

A typical reason for strong white noise during DSD playback is the use of software volume control or other PCM-based signal processing upstream of the DAC. 

Recent releases of moOde prevent the volume control issue. See the WARNING under the Volume type setting in moOde's Audio config panel

Quote:WARNING: DSD format will output 0db when using software volume

Are you using some other upstream signal processing?

FYI, some DACs support hardware volume control from moOde during DSD playback but many don't. My Khadas Tone1 board (USB) and my Inno-maker DAC Pro (HAT) do not.
