Solved: DSD/DSF - Software Volume Control doesn't work
#1
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.
