I was using the Simple EQ which gives 10 freq bands for adjustment. I use Volumio on RPi and Boss dac. I wasn’t using oversampling. I don’t have an external vol control so I use the volumio control only.
After installation of EQ, the volumio volume control showed 100% but the actual sound was low, around 20% or so. The DAC showed Boss dac via EQ. The EQ sliders were working, in the sense that the bass/treble increased and decreased, but the output level was not changing. Though the vol slider was at 100%, a display issue, I didn’t hear vol change when I moved it. I didn’t hear clipping either.
I believe you when you say that there is nothing in the uninstall script that can improve SQ. There shouldn’t be. What I observed, might have been some config issue in my system.
The improvement in sq after uninstalling is definitely there. I have rebooted and listened twice, just to confirm it. I can’t say why or how it happened, that’s for you guys to figure out.
So, as I have already said, there was ‘magic’, Which has happened for the good, so I am happy.
If you can figure out what happened and replicate the gain for other Volumio lovers, it will be great.
