I used AlsaMixer, and i'm testing the max value possible for our earpiece, RX1 Digital is now 124 on my N4


Edit:

OK, after some tests, i decided to set my value to 100, loud but clear for me. 124 causes distortions also when volume is low

Look, i don't know how to upload here my mixer_paths.xml, but in this screenshot there is the simple edit i've done ;)

And, yes, for my speaker longevity, i set again my value to 90

EDIT: After some accurate testing, i found optimal values for earpiece set to 92-93. I recommend them for everyone, absolutely no distortions at loud volume and good sound quality using V4A

Thanks for your work on this, would it be possible to upload another flashing zip with the new values you discovered to be the best ones?
Thanks

Have you tried searching the V4A XDA thread? There are several solutions there. A special v4a zip for lolli, build.prop mod zip, audio lib mod zip. Should really do some searching over there.

flashed it on Pure Nexus, yes earpiece are making the vudeo sound but it wasn't balanced, even if i put my left ear at the earpiece, still backspeaker sounds louder?

How can I control this mod? is there an app where I can toggle this on/off?
Also if i flash it, then use the revert flash, will it affect any changes made by V4A?

Does this work for Marshmallow? More importantly... What settings do you have for v4a speakers?
Yes. It works with marshmallow, hence me using it with DU 10.1.
I kinda stopped using v4a since the kernel on DU slows down when screen is off so it causes artifacts in the sound.
Mostly use it with Dolby atmos.
But it is fine. No specific settings.

Ah. Do you know also what mixer code should I change in the settings? Lineout 1 or RX1?
