I believe there was an app that simply did this for the G3 as well. I'd try it if I had a custom recovery, but I'm gonna give this a shot. Thanks!

The G4 file appears to be slightly different, did you modify all values listed?

I felt like the G4 was plenty loud as is, but I still modified a few things to get it slightly louder. Using solid explorer:

Root storage -> system -> etc -> mixer_paths.xml

You'll see: <ctl name="RX1 Digital Volume" value = xx>

Please note that certain variants may have different files. I distinctly remember Verizon G3 users had a different file to modify in order to get the sound louder. This may be the case for specific variants of the G4 as well.

I replaced all the digital volumes, from RX1 to RX8 to 90 and noticed a bit of a difference in everything. I'm not quite sure what each one does specifically, as the G3 had a bit this written out a bit cleaner, but 90 seems like the sweet spot for me in the G4. I scrolled down the entire xml file and couldn't really find anything else helpful (more like skimmed it, others may be able to find something).

Now if only I could get rid of the annoying feature that constantly puts the volume down whenever I put headphones in! Ugh.

Yeah, I'm actually getting annoyed by the G4 and how quiet it is. I've even started considering headphone app options or even a separate MP3 player!

I have Viper installed and it doesn't help enough...

Now, with the 'RX*' lines, I see the large list near the top of the file, but did you also change the ones that are listed throughout under the separate headings/subsections?

I actually did not. Maybe set those values to 95 and give it a whirl. I'd try myself but I'm preoccupied at the moment.

Okay cool, I'll take a poke in a bit. Just researching a bit more as I'm not really interested in getting stuck in boot-loop. lol

So, as an update... With a shotgun approach to changing values, we have a beautiful volume increase. It's stellar. Both @jesssiii are going to be digging into the file a bit more when we have time and will sort it out better.. It's a bit of trial and error, but with a good idea now.

It seems unlike the G2, jesssiii was able to use my mixer_paths.xml file without problem despite different variants. If anyone would like my terribly messy trial one to test or mess around with you can send me a PM and I'll explain what I've done a bit. Otherwise, as I said, once we have a better idea we'll share a cleaner solution!!

BTW: THIS IS ****ING AWESOME. The problems I have with this phone are slowly melting away with root. :)

I'm glad someone else found this to be of use other than me. I'll be watching to see what you come up with. Incall volume is the one I'm after.

You may need to poke around a bit then, I don't really speak on the phone often so I'm not testing anything lol.

This file is a lot more complicated than the G2 one. Judging from the other thread I'd start modifying the 'RX* Digital Volume' settings for things with the 'handset' header.


And for everyone else, so people can get a jump on, as who knows when I'm going to have time in next couple weeks...

Here you go!

This is a very scattershot approach, and it may have some unexpected results due to that, because we haven't quite refined it.

I went through and searched 'headphones' and changed many of the 'RX* Digital Volume' up to the number 94 (to make sure it was obvious which I changed). I also changed one 'SPK Amp Volume' from 5 to 8, under a 'speaker-and-headphones' heading. Also near the very top of the file I changed a whole list of 'RX* Digital Volume' values that were in a row.

What I didn't change was anything very clearly referring to something, such as TTY, USB, anything mentioning a KHz, VOIP, etc... But it is easy to find what I did.

The goal was to sit down when I have more time and figured out exactly which of the many are the ones that matter for this case of actually increasing headphones, as we had two more conservative attempts that did nothing at all.

I am using FX File Explorer (with root plugin), and it doesn't seem to have the problem of truncating files or modifying permissions, but it's good to always double check.

Good luck, and feel free to take a shot and share your results.

(I'm not responsible for any problems, don't forget to backup your file and check permissions!)

In-call volume path in the G2 was found here:
Code:
Dont set it too loud as echo will happen. Credit to dr87 for that info.

I haven't had time yet to look for this in my G4 as yet.

Also, I found the changed file linked by usreak above to give distortion at high volume. On the G2 it was said for headphones to only adjust:
Code: 
<ctl name="HPHL Volume" value="32" />
        <ctl name="HPHR Volume" value="32" />
And for speaker RX7 Digital.
Obviously this all needs more research/experimentation. Thanks @Usraek for your help and work!
