Hi there,
I am using a HiFiBerry DAC+DSP with dsptoolkit in moode audio. dsptoolkit is a python the interface that allows to control DSP functions.
In alsamixer I have "DSPVolume" as volume control. Strangely it is not affected when changing the volume in moode audio.
Does moode audio control directly the HiFiBerry DAC+DSP by software and is independent from alsamixer? Do they somehow interfere?
Thank you very much in advance
These are my moode audio settings:
This is the output from aplay and amixer:
