Fusion dsp forces mixer type to select hardware on volume options

For some reason, the Fusion dsp is forcing under volume options in general playback, for the mixer type to switch to hardware otherwise no sound. I have a pre amp so i do not need to control volume. This started happening in the last month. Any clue to what’s going on ?
