Default Speaker Volume Boost for KitKat 4.4.2

So one of the biggest disappointments I've had with just about all my Samsung Galaxy devices has been the volume output from the external speaker - especially when watching movies.

So, as someone else asked about this in one of the ROM forums, I thought I would share my little tweak with the rest of you, and show how to do it yourself so you can play around with all sorts of volume tweaks.

As is the case with most things, be careful making changes to system files - I am not responsible if somehow you change a setting that results in the annihilation of the entire human race! (but really ... the worst that'll happen is it won't change anything, or you'll crash on boot ... so back everything up, and nandroid)

Process:

1) Download and extract either the moderate, or extreme file uploaded to this post.

2) Using your file explorer of choice, navigate to system/etc/snd_soc_msm

3) Back up the file titled snd_soc_msm_2x_Fusion3_auxpcm (i just add a .bak to the end of it, but moving it to another location works too)

4) Copy/move the downloaded snd_soc_msm_2x_Fusion3_auxpcm file into the system/etc/snd_soc_msm directory.

5) Set the permissions to rw-r-r (errors and crashes if you don't)

5) Hot-boot or re-boot your phone, and boom ... the speaker is quite a bit louder.

This only "boosts" the external speaker, not the headset speaker, or bluetooth, or the headphone lineout.


Alternatively, if you'd like to know how to do this for future reference, I'll teach you! (because tinkering around is how we all learn in the first place, right?)

1) Open the snd_soc_msm_2x_Fusion3_auxpcm file in Notepad++ and search for "speaker" ... you're looking for the line that says "Comment "Speaker Rx device" "

2) Below that you'll see several values under "EnableSequence" ... you want to edit the "RX5 Digital Volume"

3) Change the default value from 66.9% to something like 75% (I used 72.9 for the moderate and 77.9 for the extreme)

Save the file, copy it over, and there you go.

I would caution against going much higher than 77.9% ... you could do some serious damage to the speaker if you go too high...you've been warned!

You can also play around with some of the other "digital volume" values under the other headers .. such as "headset device", etc.

Good luck folks - enjoy turning your amps up to 11!

This worked great! Thank you so much! Extreme distorts it a bit if put all the way up. I know this was bound to happen when tweaking the volume. so im about to try moderate also. But it definitely works.

Edit: Moderate is just right. Noticeably louder! But not that extreme for distortion to be caused. Thank you!

Glad it's working. I definitely hear you (pun intended?) about the distortion thing, but that's unavoidable. I personally only use the "moderate" boost - I'm not that deaf..yet.


You can definitely mess around and increase the volume of the line-out (headphones), and the call speaker .. if anyone wants those, let me know and i'll upload them.
