How to make your device Headphones-set/Speaker louder?

---

The problem is that i need more volumepower, its not loud

enough on my A500FU when i hear music over headphones/sets or speaker.

Because i love Metal in loud and not like a babyfart.

There many apps out, but these not working realy good for me

and the other side is when use it you have one more app on

your device, maybe runs in backround, not needed in all way!!!

---

NO PROBLEM FOR ROOTED USER!!!!

---

UPDATED WITH MIXER FROM LAST AICP11 FROM APRIL 10 FOR A5!!!

---

HOW? READ BELOW TEXT AND LOOK SCREENIES BELOW!!!

I HAVE NOT TESTED BUT I THINK ITS WORKING FOR ALL DEVICES/ROMS

WITH THE mixer_path.xml IN SYSTEM, PLEASE REPORT ANYTHING, THX!

For sure root is needed so that u can use a root explorer app, like

Root Explorer, ES File Explorer..etc with full read/write permission

Editing the file on PC is possible too, use Notepad++ or something.

For replace follow same way to file and replace it with the new

one with permission rw-r-r-- 0644, dont forget to mount system before.

When have a explorer open it and navigate to:

system/etc and scroll down until you see the file called:

mixer_path.xml

save a copy from it (just in case), open it with text editor and look

for the following lines to edit its values. There two sections in

which u have to edit lines,in both sections you need same score

Its a little difficult to find this lines, so i have do some shots

to see where u can find it, look on the scrolling line from explorer

on left side,i marked it red, or search the lines, the first three

lines u find directly in the first "area" called:

<mixer>

-

<ctl name="RX1 Digital Volume" value="84" /> maximum 95

<ctl name="RX2 Digital Volume" value="84" /> maximum 95

<ctl name="RX3 Digital Volume" value="84" /> maximum 95

-

second three lines u find under the "area" called:

<!-- Device -->

<!-- RX part -->

look for:

<!-- Play Scenario -->

and change the value from following lines to higher score,

but not higher as 95, because it can harms your ears,

headphones/sets and your speaker.look for the path to

edit headphones, headset, speaker blablabla, its named clearly.

-

<ctl name="RX1 Digital Volume" value="84" /> maximum 95

<ctl name="RX2 Digital Volume" value="84" /> maximum 95

<ctl name="RX3 Digital Volume" value="84" /> maximum 95

For lazy peeps or for looking on it everyday i have uploaded

files that are from different Roms for A500FU,but so far these

are all the same mixer files,just replace set perm and reboot.

---

When ready with editing/replace save it and reboot,now you can

enjoy LOUD music on earphones, headset, speaker etc.

---------

Some user report that they cant find the mixer_path.xml, in some roms/devices its

not available,because they use other files for it.I dont know all the names,but im

search hard to become infos about it,till now i found that in some devices u have to

look for:

system/etc/default_gain.conf

and edit for example you need more volume on speaker,headphones blbla this scores:

Speaker Digital Volume

SPKOUTL Input 1 Volume

SPKOUTR Input 1 Volume

-

But this file is not the only one in android universe of confusion,in newer phones its ok

when following folder is deleted from system and boom the music is louder.Delete this

from system/etc the file called: codec

-

On others its this what u need to change scores in:

etc/tinyalsa-audio.xml

to this:

<device type="speaker">

<path type="enable">

<ctrl name="AD Digital Volume" value="68" />

<ctrl name="Speaker Playback Volume" value="75" />

-

or u must change this filescores:

etc/snd_soc_msm/snd_soc_msm_2x

to this:

SectionDevice

Name "Speaker"

Comment "Speaker Rx device"

EnableSequence

'PRI_RX Channels':0:eek:ne

'RX4 MIX1 INP1':0:RX1

'SLIM RX1 MUX':0:ZERO

'SPK DAC Switch':1:0

'SPK DRV Volume':2:87.5%
