nah it's not the same
Basically, Neutron controls the android digital volume
To check that, play something with another software like play music.
Go into neutron and adjust the neutron volume to 0
now check android volume, you'll see that it's at 0
So of course if the digital volume is at zero , increasing the hardware level in the K.A.T app won't make you hear sound.
if you have unchecked the cascade option in the K.A.T app you need to turn android digital volume back up with the volume keys
Or you can check back the cascade option in the K.A.T app,
then keep pushing the volume up button on the keyboard or the tablet when the slider reaches maximum and the K.A.T app will be able to increase it.
as it cascades digital android volume & hardware levels.
So is it best to put the gain to 100 in neutron and use the KAT sliders for the volume?
Best option is to let the K.A.T app do that for you.
check the cascade option.
Adjust only the volume with the hardware volume buttons on the tablet or the keyboard
Do not touch the android digital volume sliders
Do not touch the app / neutron digital volume slider.
(see post #2 basically )
To make it even more complicated I'm most likley going to add the real WM8903 hardware DAC_BOOST (pre-amp) control soon
So you would basically have in the chain:
Fixed media level ==> Application filters/equalizer ==> Application sound level(controls android level most of the time) ==> Android filters/equalizer (Viper4Android and such if present in the rom) ==> Android Level
==HARWARE/ANALOG==> K.A.T App WM8903 PreAmp Ctrl ==> K.A.T App WM8903 Amp levels
The main thing to understand is that all the left side before ==HARDWARE/ANALOG==>
is software / digital, then it goes to the DAC.
