me again. another solution to making volume go beyond 100%. I found how to find the equalizer in 7. by trial and error I raised all bands to max, saved it, named it so it would be added to the "preset" list as "louder", apply and ok. now the volume slider in the tray can be reduced to 75% or less. now it is TOO loud. GOOD. tv volume and system volume are still independent as it should be. I do not know why this solution should have been so hard to find. I stumbled on a video that explained it. this is better than any volume app I tried. keep trying till you find the solution! it CAN be found!
