200PLEASE READ: I've noticed quite a few ROM devs are using my files without crediting me or linking back to this thread. I don't want people to start asking my permission or anything, feel free to use these files in your own work, but I worked hard trying to get my head round these files; finding out just what everything does and what the volume limits are. If you do use the modified files or modify your own using my guide please at least give me some credit. Thanks.
I've also made an Application that can do this for you. It can be found here.
PART 1
File: 'System/etc/default_gain.conf'
Hey everyone!
For those who remember my old volume hack on the T-Mobile G1, this is essentially the same thing! For some bizarre reason, Samsung decided to map all the maximum volume levels to an easily accessible file (system/etc/default_gain.conf), which is different to 99% of Android phones out there because it's usually built into the kernel or something harder to modify. Cheers Samsung!
THIS MOD WILL MAKE THE PHONE'S SPEAKER AS LOUD AS THE OS ALLOWS. ANY LOUDER AND THE AUDIO BREAKS! YOU HAVE BEEN WARNED!
Things this modification can achieve:
There are a few others in that file too. It's weird that instead of defining the Headset Volume for everything, things like 'incall' and 'FMradio' are all separate.
How To Modify
Any text editor will do but I strongly recommend Notepad++ because it's just awesome!
How To Apply
1) Download attatched file ('default_gain.conf' inside 'VolumeMods.zip')
2) Use a file manager or ADB to push it to "system/etc" (back up existing file first!)
3) From ADB or the Terminal do:or reboot your phone!Code:killall mediaserver
4) Enjoy
PART 2
File: 'System/etc/Volume.db'
This isn't really an audio hack as such, it simply allows you to disable some irritating sounds you cannot normally disable.
What this mod disables:
All this is so far useful for is to disable the camera sounds without modifying the camera itself.
There are most likely other things this file can do but I've not had chance to play with it properly yet, I'll keep going and update this post if I find anything else.
How To Modify
I strongly recommend using the free "SQL Lite Databse Browser". Any program that can open .db files should work just fine though.
How To Apply
1) Download attatched file ('Volume.db' inside 'VolumeMods.zip')
2) Use a file manager or ADB to push it to "system/etc" (back up existing file first!)
3) From ADB or the Terminal do:or reboot your phone!Code:killall mediaserver
4) Enjoy

60_sound_mod - max vol = 60 (boot sound on, camera sound off)
63_sound_mod - max vol = 63 (boot sound on, camera sound off)
63S_sound_mod - max vol = 63 (boot sound off, camera sound off)

As the name suggests, this extra little mod (to the same file) will increase the volume even higher. Seriously high. I wouldn't recommend doing this as it distorts to hell and will most likely damage the speaker in the long run.
For those of you crazy enough to give this a go, here are the instructions:
1) Take the 'default_gain.conf' file (attached to the first post)
2) Search for the following section:
and then look forCode:Modifier "Normal" { Supported Device { "Speaker" } Enable {...Change the value after that to whatever you want. The highest I've dared to go is 55. 55 is PLENTY loud enough, but you can probably go higher.Code:{ "AIF1 Boost Volume",
DISCLAIMER
The volume is getting absolutely ridiculous now. Be seriously careful if you decide to do this because it can go insanely loud and will most probably damage your speaker. You have been warned!!
Enjoy5
Thanks
The file is incredibly detailed and each individual parameter can be changed.
I'll list here everything I know about the file.
It's basically split up into 2 sections: The "Output Modifier Stage" and the "Input Modifier Stage". So the output stage controls volume and the input stage controls microphone gain, essentially. Under each stage you have a list of "Modifiers" and under each modifier you'll have the "Supported Devices".
Here is the complete list of modifiers for the output stage (we're not interested in the input stage for now*):
And here's a list of the devices for the Output Stage (many more in the input stage!):
So how do we use this information?
Well, let's say we wanted to boost the in-call volume:
As mentioned above, there are 2 things we need to keep an eye on; "Modifier" and "Supported Devices".
So say you wanted to boost the volume during a call but only for the earpiece (and not for the headset, bluetooth, etc). Well, we find the correct modifier, which is "Incall" and then we find our correct device, which is "Earpiece". We navigate to that little section, find the "Output Volume" and increase the value!
For "Speaker" related sections the value will be "Speaker Volume" and for the Headset it will be "Headset Volume". There may be other variations too.
Now, for your question; Boosting the headset volume:
For this we need: Modifier "Normal", Supported Device "Headphone".
So, we search for this section (it's not very far down) and increase the value!
The section you are looking for should look like this:
Code:Modifier "Normal" { SupportedDevice { "Headphone" } Enable { { "Speaker Mixer Volume", 1 }, { "Speaker Volume", 0 }, { "Headphone ZC Switch", 0 }, { "AIF1DAC1 Volume", 96 }, { "AIF1 Boost Volume", 0 }, { "DAC1 Volume", 96 }, { "Left Output Mixer DAC Volume", 7 }, { "Right Output Mixer DAC Volume", 7 }, { "Headphone Volume", 50 }, }
Headphone Volume is the value you need to change.
Please note: If your headphones double up as a headset (you can place and receive calls with it) the phone might recognise it as "Headset Out" instead, I'm not sure. Probably better to change both.
So you can match each modifier up with each supported device and create a very complex audio configuration file.
For example, match up the "Ringtone" with the "Headset/Headphones" section and you can control how loud the ringtone plays through the headset when a call comes in! This file's pretty in depth
We also now know that there is another volume controlling parameter called "AIF1 Boost Volume". This can boost the volume even further than you can with the normal "Output Volume" values, etc. (see post 2).
*Whilst we're not interested in the "Input" stage for this mod, it could be incredibly useful for tweaking microphone sensitivity. You can alter the input gain for during a call and for when you're recording a video.
This is my interpretation of the file. Whilst I know some of it is correct, some of it could also be completely wrong, there's just far too much to test. Please go easy on me if some of this is wrong!5Loud it is..
But Distorts stuff!!
Any ways if you want to Flashey Flashey use the file below... flash via CWM
