2. I meant that I have a customized equalizer preset which when saving, also apparently included a custom tone(bass & treble level controls) set up. When I change from this custom preset to a default preset equalizer, the tone settings still remains unchanged. I have to manually click on reset button to tone everything to default.
I've attached a screenshot of my custom equalization preset (LARSTY) showing that when it saved this custom preset, it included tone customization (bass level of 77% and treble of 61%). If I change to a system preset, these two still remains the same.
