DSD/DSF - Software Volume Control doesn't work - Gianni Ovalsand - 12-04-2019
Hi,
I am running a RPI 3B+ with a JustBoom DAC HAT + Moode 6.4.0. I typically plug my headphones directly into the DAC HAT but I've noticed that the software controlled volume doesn't work when I play a DSD or DSF file. It works fine for FLAC or mp3. When a DSD or DSF song plays, it plays at FULL volume regardless of what the software volume is set to (i.e., 1 - 100).
Am I doing something wrong with the audio setup? Has anyone else experienced this on this DAC or any other DAC?? FYI, in my last setup, I used Volumio and was able to control the playback volume via software of DSD files.

No, nothing wrong.
MPD has no code to change volume of DSD.

Try changing to MPD Hardware volume if the audio device support it

SOLVED - Thanks Tim!! Works perfect. For some reason I thought "hardware" meant the volume was controlled by some sort of potentiometer on the DAC.
