[T-Mobile Galaxy Note 4 Android Development] jazzmachine:
Hey man, thaks for checking out my post and props for trying out the Dolby mod. I can gladly elaborate on that :) First I'd definitely recommend (if you haven't done so "recently enough" already, making a nandroid before changing those files). I actually was also kind of worried about replacing specifically the file that you mention, for the same reason. The concern that replacing audio_effects.conf might break V4A (minimally, thought it might break other "audio output" elements on my phone as well). That was one of the main reasons that I renamed the files (specifically in that case from audio_effects.conf to audio_effects.conf.bak) rather than just "replacing" them. I was actually quite surprised when using the verson of audio_effects.conf packaged with the Dolby mod didn't seem to effect anything... that is, V4A worked the same as before (tested both checking the driver status in the V4A app while playing music, as well as my ears), FauxSound seemed unaffected (tested by toggling it on and off and noting the difference in sq), and all other audio elements seemed fine (as far as I could tell at least... if you decide to go through with the Dolby mod I'd much appreciate you letting me know if you notice any problems that I may not have.) I feel like I should mention that my DK 4.2 installation is pretty heavily debloated, i.e. I don't use nearly all of the "baked-in features". It's definitely possible that this installation might affect something that I haven't noticed since I've removed it from my phone. By that I mean that manual installation of the Dolby mod on a N910T should definitely be considered "experimental" and/or "at your own risk". :angel:

Anyway, something to note if you do get the Dolby app installed and working, the only part of the app itself that doesn't work (again, as far as I've noticed) is the "Play Demo" function. I'll attach a screenshot of the app (with a track currently playing via PowerAmp) so that you can see what I'm talking about/get a sense of how it works. I took the shot with music playing so that you can see that the visual equalizer at the top does work. Other things to take note of: there are different settings for each "type" (see pic) of sound. In order to change the settings for the different sound types you need to tap the button once to switch to the "equalizer" for the type of output that you want, then tap it again to alter the settings. Related to this, I'm... pretty sure that, say you want to use the settings for playing a game, the Dolby app doesn't auto-detect that you launched a game and apply those settings. Rather, if you are going to play a game (and want the Dolby Game settings active), you would have to open the Dolby app, and tap on Game to switch to that output.

BTW, if a more thorough, step-by-step, "How To" style list of steps that I took to get the app installed would be helpful (for you or anyone else who's interested) just let me know. I would just need to find where I saved the file and unzip it to recall the exact steps I took to write them out; not a problem :)
