Changed all the RX1 / RX2 from 88/84/81 (defaults) to 92. Seems to be working fine.
Nice to hear it's working on your end. What's really confusing me is that devices have different paths that seem to work on them and I can't see any similarities. You seem to be using an H815 while I'm on H818. :confused:

Most "loud speaker" mods edit the "<path name="speaker">" however it seems commented out in LG's file, and there is a different section:

Code:
    <!-- Start LGE Speaker For TAS2552 AMP -->
    <path name="speaker">
        <ctl name="Speaker Driver Playback Volume" value="9" />
    </path>
I'm pretty sure that lowering this value, would increase the sound. I set it to 24 and speaker is quiter when pressing volume up. I then set it to 5 and it was quite louder. Searching about the amp, it seems that The minimum volume level for the TAS2552 (control register value 0x00) is -7dB.

For the other values, I just changed all "RX1 Digital Volume" and "RX2 Digital Volume" to 92, instead of the 80/81/84 I found throughout the file. Just need to work on the external speaker now.

Posted info on my current attempt at bottom of OP. Still very disappointed, and also a little bit sad that nobody has found any better solution. The output on this phone really is terrible, though in comparison to some other phones like the Z3 it's much better.

*sigh*

EDIT 04/FEB/2016:
Just followed my own tutorial again. It all functions on 5.1 with an H812. This time I set my RX volumes at '89' and my HPHL/HPHR at '21'. They seem to function independently just fine, so you can try one or the other. I tried higher values on each and the distortion is just gross. Even on these numbers I may need to tweak again so I can comfortably set volume on max without distortion worry. It really does depend on the track too, as there's less range needed with some genres.
I think you may have an issue with your source material or else your headphones - All I did was I set several of the RX1 and RX2 entries in the mixer_paths.xml file to the settings shown below and wow, it sounds fantastic with volume maxed! - Now to reiterate, when you are that close to the clipping level of the internal small amp, there is no tolerance for any crap, such as the following:

● mp3 files
● mp3 320 files
● aac files
● other lossy crap files
● in-ear headphones
● Beats headphones
● other junky headphones

and it is not even enough that your files are a lossless format such as FLAC, WAV, or AIFF - you also need to ensure that the songs were ripped correctly with good equipment using Exact Audio Copy (EAC)

if your headphones were not built by one of the following companies, there is a good chance that you need to rethink your choice of brand:
(alphabetized by country where the firm is headquartered)

Austria:
● AKG

Germany:
● Beyerdynamic
● Sennheiser
● Ultrasone

Japan:
● Audio-Technica
● Denon
● Fostex
● Sony
● Stax

USA:
● Audeze
● Grado

China:
● HifiMAN


I am using:

all FLAC files ripped with EAC
Fostex T50 mk3 headphones with ZMF cowhide pads
Jet Audio player - no equalization

As far as the built in speaker on the back of the phone, it is not designed to play any louder than it does stock, so trying to increase the volume of it, is silly.

my settings:
line number within the mixer_paths.xml file is shown first

Code:
29 = <ctl name="RX1 Digital Volume" value="91" />
30 = <ctl name="RX2 Digital Volume" value="91" />

2467 = <ctl name="RX1 Digital Volume" value="91" />
2468 = <ctl name="RX2 Digital Volume" value="91" />

2475 = <ctl name="RX1 Digital Volume" value="91" />
2476 = <ctl name="RX2 Digital Volume" value="91" />

2483 = <ctl name="RX1 Digital Volume" value="91" />
2484 = <ctl name="RX2 Digital Volume" value="91" />

and so on.....

2496 = 87
2497 = 87

2504 = 89
2505 = 89

2530 = 87
2531 = 87

2538 = 89
2539 = 89

2546 =87
2547 =87

2554 =89
2555 =89

2563 = 87
2564 = 87

2571 = 89
2572 = 89

Can anyone confirm that this works on the H811 (T-Mobile USA variant)? I'm assuming it does, so maybe share a quick experience if it does work for you? I've tried editing the .xml file in the past and removes all sound from the device until I restore the default. Also, something that kills me is the LG V10 is nearly the same specs (not talking about the secondary DAC, just the SoC DAC) and there's an amazing volume boost that worked (found here in the V10 forum - wont let me post the url) and I'm assuming this modified xml file does nearly the same thing.

My goal is to boost the gain with the xml mod and use V4A. That's the only reason why I keep the massive V10 around.

Thanks in advance!

I need to respectfully request you add Bang & Olufson to this list. I have a pair of H6's and they are simply incredible with very minor equalization adjustments (to personal preference, of course!) They list for $399, Amazon has them new for $350 and I purchased a set from Media Mart in The Netherlands for 225 Euro. I typically listen to music with my Audioquest Dragonfly v1.2, FLAC files and USB Audio Pro on Android.

I'm just now starting to get into FLAC files. In the past it was silly to have on the go music in the form of FLAC simply because there wasn't enough storage space. Now that 128gb (and even 200gb) microsd cards are affordable, seems only logical to give it a try. IMO, it's silly to listen to FLAC anywhere but a dead silent room, no matter what the choice of headphones are. Which brings me to the question, isnt FLAC a direct copy of the audio source in binary? If so, does it matter what application pulls the 1's and 0's from the source to the container FLAC file? To hear imperfections in the actual music recording to me is what I'd consider "entry level audiophile" critical listening and a joy when you're in a quiet enough room to hear that, but I don't see how a portable source like a cell phone would have any impact on how the FLAC file was created.

Also, the xml adjustments you made.. were those of personal preference or do you have testing equipment to verify they are as close to the original as possible? Again, I ask because in my quest of FLAC listening I'm trying to find as close as possible to the actual recording so I can see how the artist intended on playback and then I can make my own personal adjustments.

Thanks in advance!

find out who actually builds the headphone for them (who makes the driver)

FLAC or other lossless format, such as AIFF, WAV, sound better regardless of ambient noise, dead silent room or noisy room, both environments will sound much better with a lossless format, properly ripped

- lossy formats such as MP3 and AAC (iTunes) have over 90% of the original file removed and do not sound very good on decent equipment
and yes, the method of ripping those 1's and 0's is important, to preserve the integrity of the original, the pros use a free program called Exact Audio Copy (EAC) to rip a CD direct to digital and preserve the file audibly and mathematically perfectly.

also, keep in mind that once a file has ever been converted or ripped to a lossy format, such as mp3 or aac or wma etc., the audio quality is lost forever, and no conversion can bring back the great sound

Also, the xml adjustments you made.. were those of personal preference or do you have testing equipment to verify they are as close to the original as possible? Again, I ask because in my quest of FLAC listening I'm trying to find as close as possible to the actual recording so I can see how the artist intended on playback and then I can make my own personal adjustments.
the adjustments in the XML file that I made only affect maximum volume, not the integrity of the music itself - however, you can adjust these settings too high and that will make it possible to overdrive the phone's internal amplifier into "clipping" which would make it sound like crap at high volume - the original files settings are designed to protect your ears from very high volume levels, but with very inefficient headphones (such as Fostex T50RP mk3) this causes the max. volume to be far to low.

Hi!
I followed the guide and edited the mixerpaths file to 90. Worked fine at first.
But i have a problem with it:

The max Volume is not always present - I often have to unplug and replug the headphones to it to get louder. Volume always on max. But not always the same volume - yes same track and player.

Do you know how is that even prossible?

Hey!
Does anyone know anything about good settings for the European H815 with V20d 6.0 firmware, maybe some other setting than headphones-advanced?
I'm changing the settings under headphones-advanced and anything over 84 on the RX settings seems to distort on max volume, also the HPHL/R doesn't seem to do anything, I've tried changing all the way up to 24 but I can't seem to hear any difference at all, not even distortion.

This is pretty disappointing since my old G2 was putting out a ridiculous amount of distortion free power after I modded it and this one barely goes beyond stock.

Edit: I tried and compared some more, it starts distorting at 85 with Koss Porta Pro and at about 87 with Sony MDR-XB500, both of which my G2 can drive a lot louder and cleaner. That would suggest the amp is too weak to handle higher settings anyways. What a bummer....
My test track was Makeup by Neelix, it has a really hard and clean kick and bass beat at about 6:30 that seems to bring things on it's knees if you want to compare.
