This mod was made by sshafranko and with his permission I am posting this here on the note 4 side.
If you place your Note 4 on a table or a couch while listening to music, the sound becomes almost completely muffled. If you feel that you could use a bit more in the sound department from your Note 4 you will love this mod. I use my phone for basically everything it can be used for, truly replaced my lap top with my phone since my Note 2, and one of the first things i have always done is my sound mods to increase speaker volumes and install Viper for some improved audio goodness. This time around i decided to do a bit more and take it to the next level.
This mod will activate you front earpiece speaker in conjunction with the rear main speaker any time Speaker mode is used for example playing music, watching movies, shows, you tube and so on, creating an almost surround sound type of effect. There will be three zips to flash in this post and they are as follows:
1) Stock volume values approximately 84 with activated surround sound type effect.
2) Very Loud volume values approximately 90 with activated surround sound type effect.
3) Revert back to stock sound volume values and stock speaker functions and effect.
This modifies the mixer_path.xml file in you system/etc folder. This .xml file varies device to device and even carrier to carrier. I have not tested this on International or any other carrier note 4, and i used the T Mobile .xml file as my base. Therefore i don't know if it will work on any other carrier although i will say that there is a better chance of it working on another U.S. carrier than there is on International. If you decide to try it please have your rom backed up in case of a boot loop, and before you flash the zip or extract and push the .xml file to your system, rename your original mixer_paths.xml to mixer_paths.xml.bak so that you have your original easily accessible. There is a slight chance that if you pm me your mixer file i can mod it for your variant, and maybe add it to the thread assuming it doesn't work for you and i have some spare time.
A Rooted Galaxy Note 4
Custom Recovery Installed. I tested on TWRP 220.127.116.11
A set of human or alien ears (animal may also work but have not been tested by me)
I am not responsible in any way, shape, or form, directly or indirectly for anything good or bad that happens to your device do to your modifications using my surround sound zips. Please do not inject, ingest or insert these zips anywhere on or in your body, they are meant to be flashed in a custom recovery on your Note 4 Beast.
STEP 1: Download the sound mod zip of your interest and also Download the Revert to stock zip. (Optional) If they end up on your internal storage, navigate to the zips using a root explorer such as Root Explorer or ES Explorer, etc. and copy the zips over to your ext. sd for safe keeping.
STEP 2: Boot to recovery by using modded shut down menu, Power Toggles type Widget, or simply turn your phone off. Once completely off hold Home, Volume up and Power buttons simultaneously which will then boot your recovery.
STEP 3: Navigate to the Sound Mod Zip of your choice and flash it. I don't believe it is necessary to wipe caches with this type of mod, but i would suggest it. Any time i am in recovery i take the opportunity to wipe caches and fix permissions, almost as a maintenance type of habit.
If you used CF root to root your phone you may be having some issues mounting the cache partition. There are 2 ways to fix this, both worked for me, the first of which may or may not work for you and is very simple to try and the second more involved.
1) Wipe Dalvik Cache ONLY. Now wipe Cache ONLY. Now wipe both Dalvik Cache and Cache. If this worked for you, you will now be able to wipe caches without mounting errors.
2) Begin from scratch and re-root your phone except this time DO NOT use Chainfire's CF Root. Odin TWRP recovery, make sure you have a zip of SuperSU 2.16 i believe it is on your sd. Once TWRP is odined, boot to recovery and inject (flash) SuperSU. When booted you will most likely be prompted to update SuperSU as i believe there was an update today, assuming you are injecting 2.16. These steps are only for those having troubles flashing do to CF Root braking TWRP. If this has been fixed, i apologize and please ignore, as i have not checked today.
Post your experience with this mod here, any issues, requests and so on, and i will try to get back to you as soon as time allows. Happy flashing and i hope you all like it. It took me 5 hrs to figure out the correct code for the device and play scenarios in mixer_paths to get this working correctly, and a bunch of testing to get it bug free but well worth it. Hope you guys share my enthusiasm with this mod.
Known Bugs: Sound plays from earpiece speaker while headphones are connected. FIXED
Please let me know if you find something i missed. Thank You.
DWITHERELL-You are the best. Thank you for zipping it all up, and listening to all my dumb comments and questions...
