TIP #1:
If your G2 stock earbuds fit your ear canals really well, see if they fit on your other earphones!
I tried these G2 ear buds on my ie-80 in-ears and i can honestly say they give the best seal i have had in 7 months since getting these earphones!
The G2 buds have an abnormally large hole diameter which allows alot more high/mid range through than my previous sets. Stoked!
TIP #2:
Clean your in-ear headphones regularly, scotch tape works great!
Pull off the earbuds and carefully dab (do not rub) each the earphone housing speaker grills repeatedly with sticky part of the scotch tape to remove any wax/dirt buildup.
Repeat this once every 1 - 2 weeks to ensure longer life/good sound of your earphones.
If possible store your in-ears in a clean container/sealed carry pouch so they do not collect dust/lint/dirt from your pockets.

Thanks for the mod. Tested a FLAC song with stock music player on speakers. Max volume and no distortion.

Great to hear!
On a note of personal note, i had viper4android installed on my LG G2 but with these modifications,
i ended up uninstalling it as i was primarily using it for volume boost purposes as opposed to signal shaping/eq-ing.
I also found that viper4android would work randomly with some files but not others.
IMO Volume boosting should work consistently at all times, across the board.
From the purist/consistency train of thought this volume mod will give you consistent volume boosting and more power to your headphones (fuller sound) without altering/degrading the already superb audio signal, or adding digital noise.
That being said, viper4android is a great app for shaping the sound signature, which is what it is primarily designed for.
For me, "the closer to the original source, the better"

Much improved sound. Thanks.

This is an external Speaker and Headphone Volume level modification.
It is what I feel "should have been" the stock "happy medium" audio levels for the LG G2.
The DAC audio quality coming from the LG G2 is excellent.
This modification brings the listening sweet spot down to 50% volume level instead of the 80-90% volume range at stock.
Stock levels did not push test headphones as well.
Benefits:
- Removes the need for 3rd party audio VOLUME BOOST apps
- Does not alter DAC raw audio signal quality
- Provides optimized signal drive for higher ohm headphones
- Improved audio fullness
- Improved low end at optimal listening levels

2. Locate the file called: "snd_soc_msm_Taiko"
3. Copy this file to your storage as a backup in case you decide to revert back to stock.
4. Download the "snd_soc_msm_Taiko" file to your phone: http://www44.zippyshare.com/v/67179492/file.html
5. Once complete, paste the downloaded "snd_soc_msm_Taiko" file into: /system/etc/snd_soc_msm

Permissions should not make a difference in this case, however you can set them to rw~r~~r~~ for the file as shook mentioned using root explorer.
Mine are currently set to rw~rw~r~~ and there is no difference in performance.
I have updated OP with step 6 as optional. Cheers!

Really.
Well not giving thanks where its due, is even more lame, not to mention it is Thanksgiving today after all..
1. For what its worth i stumbled on this file in my G2 looking through sys etc files as a result of modding my note 2 last year in similar fashion, when i was looking for volume boosting without 3rd party apps at the time.
2. I have spent time testing to ensure i get the levels right on a fair range of equipment, and i feel others should be entitled the chance to benefit from this as well.
3. That thread that i ended up finding (and linking out of courtesy regardless) is pretty convoluted and a bit of a mess, labelled ATT (i am on Bell and this is a universal fix, not just ATT), and realistically only addresses speaker volume.
4. I have provided a working tested version of the file that G2 owners can use if they choose; not everyone is comfortable/has time/patience to edit/test settings in order to enjoy the untapped potential their phones have to offer.
5. I was in actuality not soliciting (seeing as we are NOT selling anything here), but making a factual observation through my thanks post, and the same applies to all positive dev/mod work.
You're welcome.

thanks, audio seems improved and much higher.
maybe a bit too high.. I can't set volume up to middle.

The version i posted on this thread works fine with no issues.
I have tested the scenarios detailed in your post using 2 different cell phone lines, calling my g2 from another cell, and vice versa.
Both with speaker mode enabled/disabled, and with/without headphones.
Mic works fine in both cases for me, no issues here on my Bell version G2.
I do not currently have a pair of headphones with microphone built in to test that format though, if anyone else can test that would be great.
Please clarify carrier, whether phone is stock or not,whether has he done any file edits after the fact, etc.

Increase Audio Levels

I have tried Hashcode's CM 10.2 and 11 but both seem to have the same problem with very low audio levels out of the built-in speakers. It seems that at 100% I'm only getting about 1/2 - 3/4 the volume I experienced with the stock Amazon ROM when using apps like Netflix, Youtube, HBO Go, etc.
On top of that issue I've also found that none of the volume boosting apps on the Market, which worked perfectly with the stock Amazon ROM, work with Hashcode's CM builds. I've found some threads for modding CM files to boost audio but those files don't seem to exist in these Kindle builds.
Does anyone have any ideas on how I might boost my audio volume? Thank you in advance for any help you may offer!

OK there is a file you can adjust but I would recommend installing viper4android. I Don t have a link to the thread but Google it, it will probably have the first result being an xda thread, follow its instruction for the extra times you put on the sdcard, but other than that just install it, I wouldn't worry about the stuff it says to check for in the built.prop and putting it in the system apps folder. Long story short not only will this increase your audio output, you can also add immense am mounts of bass and stuff. Amazing app.

This worked for me, I did find that those settings made it a bit too loud and it distorted pretty badly so i tweaked it down a bit and it was much better! Netflix is a tolerable volume now, music needs to be kept a bit lower though.

120-100-4 respectively has been working out fine for me.

Increase volume

As our zenfone 2 are realy good. they lack strengh of volume.
I have found this thread about others zenfone. Can a master take a look. And adjust it to our phones.

Thank you.

yes, how????

I don't have any problem with volume of speaker but earphone volume seems a bit low when using poweramp

Yeah, I was wondering how to increase the volume even more, especially so that I don't miss important calls or texts.

the volume is lowest ever made on smartphones! any tweaks??

Viper does nothing for volume

The other day I discovered that I can change the headphone and speaker gain on my Samsung Galaxy Tab S tablet by editing /system/etc/default_gain.conf. This worked on Lollipop and KitKat.

You need root, install es file explorer, enable root mode, mount /system rw from ES, then edit that file with ES file editor, and reboot. Then if you don't need root anymore, you can mount /system back ro, disable root mode, and do full unroot from supersu settings. I have no idea if the same works on other devices, but you can try.

I don't have any problem with the volume quantity but the quality.... Noise gets distorted above 80% .. Ringtones,mxplayer,music in every thing.
I owned 2 Z00A models both of them had the same problem.
Even tried other custom roms.... That also didn't do anything.
Do anyone else face this issue ?

It is not possible that some of you say that you have no issue with the sound volume . me and my friend just bought two zen2's and both of us had other phones before and we were veeerry surprised when we heard the super low voltage on zens .
Huggge difference compared to g3,huwawei mate and htc 8.
There was this tweak for g3 to edit mixer_path.XML and the volume gained like 50% loudness that was incredible. Is there any way to do the same with zen2?

I would beg to differ. I can't remember which settings I tweaked, but here's a guide for the older version of Viper4Android:
http://freaktab.com/forum/tablet-su...-louder-on-android-devices-viper4android-root
Should be along a similar path.

Alsa Mixer is the solution, but root is reqiured. Just install Alsa from play store and modify RX1 Digital to RX7 Digital.

Alsamixer isn't working for me. I get "cannot link executable: cannot load library libasound.so

Increasing headphone volume?

Hi there!
I'm just wondering if anybody knows how to increase the volume when having headphones connected. I've already installed Viper4Android yet I still find the sound to be rather insufficient... I've tried swapping some values in mixer_paths.xml but the changes won't stick after a reboot... Just curious if anyone has an idea or something?

I use VLC player for music on my microSD card. In advanced settings under Audio out change to OpenSL ES. The sound is much louder.
But only in VLC, not other apps.

Possible solution
Hi again guys!
I think I might have found a solution to the insufficient audio the solution was editing some values in mixer_paths_mtp

Sound too low

Hi all,
In my previous android phone (samsung s3) I had the same problem, but i solved it with root and edited a simply file into system to increase (i think) decibel.
With my rooted OP3, i tried to edit a similar file like in the samsung s3 with no results, then i have install viper4android and EX kelnel to boost audio, but the sound increases distorting the file....
Do you have a solution.... ?

Can you give me link?
I found a thread, but viper4arise give me: i/o error
Edit: Installed with success, but it seems like viper4android.
The problem come when i raise the volume, the bass are distorted.
I usually download mp3 from youtube at 320kbps, i tried also other way like torrent, but audio quality looks the same.
Can you give me a suggest to download music at the best quality? Also if isn't mp3 extension.
Thank you.

Find an appropriate setting for your Headphone in viper4arise. Download kernel files and select in the convolver option, u can get it by a simple Google search.
