[Android Software Development] ShadoV90:
So, Lither. If you are using Dolby Atmos and have that... "issue" then you are probably using 6.5 Atmos (pretty old lenovo port) and you are probably using custom 1 or custom 2 profile. In /system/etc/dolby you should have file "ds1-default.xml" or "dax-default.xml".

When you open it you will see configuration of Dolby Atmos app.

Here's example of that... old Atmos entry:

<preset id="ieq_open">

<data>iebt=[117, 133, 188, 176, 141, 149, 175, 185, 185, 200, 236, 242, 228, 213, 182, 132, 110, 68, -27, -240]</data>

</preset>

lower:

<profile id="user2" name="Custom 2">

<data>aoon=[2] dea=[7] ded=[0] deon=[0] dhrg=[0] dhsb=[48] dssb=[48] dssf=[200] dvla=[5] dvle=[0] dvme=[0] gebg=[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] geon=[0] iea=[10] ieon=[0] ngon=[2] plb=[0] plmd=[4] vdhe=[0] vmb=[144] vmon=[2] vspe=[0]</data>

<include preset="ieq_rich" />

</profile>

and near on bottom of file:

<constant>

<data>aocc=[2] aonb=[20] arnb=[20] dvli=[-320] dvlo=[-320] dvmc=[0] gebf=[43, 129, 215, 301, 431, 603, 775, 947, 1206, 1550, 2067, 2756, 3618, 4651, 5685, 7063, 8958, 11025, 13781, 18777] genb=[20] iebf=[65, 136, 223, 332, 467, 634, 841, 1098, 1416, 1812, 2302, 2909, 3663, 4598, 5756, 7194, 8976, 11186, 13927, 17326] ienb=[20]</data>

</constant>

When i tested settings by trial and error method i "decode" these shortcuts of names xD

aoon = Audio Optimizer ON (better stays on 2, it affects sound pretty much, when you change it to 0 or 1 it will lose all bass)

dea = Dialog Enhancer Amount (can be tuned up to 10, it gives clearer voices and louder trebles)

deon = Dialog Enhancer ON (1 means on, 0 means off by default, you can ofc turn it on manually in app)

dhrg, dhsb,dssb, dssf they affects sound stage i think when you activate surround virtualizer

dvla = Volume Leveler Amount (i think it's how much responsive that thing is)

dvle = Volume Leveler Enable (by default, ofc 1 - on, 0 - off)

dvme = Volume Modeler Enable (i don't know what that thing do)

gebf and gebg = Graphic Equalizer Band Frequency and Graphic Equalizer Band Gain (you can manually add "strength" of that frequency without doing it in app and without touch other frequencies like in app)

geon = Graphic Equalizer ON (by default, 0 or 1)

iea = Intelligent Equalizer Amount (from 0 to 10, larger value means stronger effect of int equalizer like open, rich, focused)

ieon = Intelligent Equalizer ON

iebt = Intelligent Equalizer Band Tuning (these numbers affects strength of bands listed in iebf section (bottom part of file))

ngon, plb, plmd - i didn't discover what that means

vdhe = Headphone Virtualizer ON (by default)

vmb = Volume Maximizer Boost (range from 0 to 255, larger value means louder output of volume leveler)

vmon = Volume Maximizer ON (So, if you have value 1 or 2, then when you enable volume leveler, then it will try to maximize volume output, and here you can turn it off by change it to 0 or set vmb value to lower number)

vspe = Speaker Virtualizer ON

If you are using that version of Dolby Atmos, it's software effect without hardware support, so that effects are kinda artificial. If you have an opportunity, better get Dolby Atmos with hardware support. Sound is much more natural and overall better, and volume leveler isn't like (i will turn volume to max mwahahahaha! COVER EARS DUDE!!!)

And one more thing. After edit that file, you must reboot your device for apply changes. Soft reboot is often enough.

I hope that things which i tried to explain are clear.
