MOD>Manually Boost Volume for Speaker, Headset and Handset<MOD - T-Mobile Samsung Galaxy S 5

GUIDE TO MANUALLY RAISE VOLUME
Must be rooted and have a file explorer installed. Each step has a corresponding numbered picture.
.......................................................................
I found that the speaker, headset and handset volumes were a bit too low for my damaged ears, so I decided to attempt changing it myself and it worked out wonderfully. (Same method I used on my N3) .......................................................................
I did this using Root Explorer, there are many out there you can use such as ES.
1) Navigate to System/etc. Scroll down to mixer_paths.xml. If using Root EX on the top right tick Mount R/W. If you dont do this your changes will not work or take.
2) Hold down mixer_paths.xml and a box with options will appear. Choose Open With. Then choose Text Editor.
3) Once it opens scroll down to the fourth divider line where you will see this:
Play Scenario
Then you will have a bunch of small paragraphs. First one directly under the Play Scenario line is "handset", then "speaker" and finally "headset". There are others like dock, speaker hdmi and so on but I only changed those three.
4) In each of the 3 you want to change the "RX Digital Volume" values. Stock value for the handset is 81. Touch next to the 1 delete it and inplace put a 7. (I found that 89 is the limit on my phone before distortion starts to occur so 88 or 89 is fine also) Next is speaker. Do the same 81 to 87 or whatever you prefer up to 89. And finally headset. For this change both stock "80" values to 87. (Left and Right) Double check all four changes you made closely. If you change the values above 89 there is a chance you may exceed the limit and have issues like no sound for the specific play scenario.
5) Now hit your phone menu button and tick save and exit. This will bring you back to the mixer_paths.xml page, and if you mounted r/w as I stated in step 2 you should see this directly below mixer_paths.xml: mixer_paths.xml.bak. That is a saved copy of your original stock mixer_paths.xml file which you can delete the modded and remove the bak from the name and reboot to revert to stock if an issue occurs such as no sound. Great
6) On top right you should see Mount R/O this time. Tick that and if it doesnt change dont worry it sometimes doesnt, reboot immediately. Once booted up your new values will be implemented and speaker, headset and handset will be much louder.
If you decide to mod the values once again, the saved file with name .bak created will be of your previous setting not stock. It will override the stock saved file. So if you plan on doing more than once to get the best desired volume, after your first ever edit, hold down the file created with .bak in the name and copy it to you extsd for safe keeping. This will prevent you from posting I lost my original file can someone please post it here?

Looks like flashable zips for this mod were already posted by DustinTinsley in the Development thread. My fault I didnt look around before posting this. Mods please delete this thread as it seems to be unneeded. Thank you.

Thanks for this guide. Well done. I also prefer to do this manually. So to go back to stock, rather than restoring the original mixer paths xml file, can I simply edit the values back to 80 and 81? I backed up the original file as you suggested.

You can but the easiest way to do it is add the .bak to yhe modded mixer, then remove the bak from the saved one reboot and now your on stock sound and youll still have the modded in there saved just in case. Just be sure to tick mount r/w before you rename and reboot. Glad it helped you.

Got it. Also it makes sense that if the values are changed a second time the bak file that was saved will be overwritten. Found this on the thread for the volume boosting zip thread. I will give these a try too

Exactly...thats why switching the .bak between the two is easiest.

Cool man. Thats kind of who this is geared towards and also people like me who like to learn to do things instead of just flashing something and not having any idea what that flash just did to your phone.

Lol I did it it sounds low what's the max it can be modified to? Jelly bean had distortion but I never maxed it out. What's the highest I can put it without messing it up?

im assuming it all depends on your phone. start out at 87 and put your volume up, if its distorted or sounds like its going to break something, then change the number down a little at a time till it fits your needs. my numbers were a little different than the OP's numbers.

Guys it seems like it varies a bit phone to phone. On my wifes phone I am able to go to 90 buy it distorts at full volume. So I backed it down to 89 and it is perfect for her. I tested it on 91 on her phone and it actually broke the volume. She lost the volume completely on speakerphone. So im pretty sure that on every phone therre will be a setting that is too high and brakes volume. I would stick to 90 as being the highest than work your way down until no distortion. If 90 is not loud enough than give it a shot on 91 or even 92. It may work for you but like I said 90 was max for my wifes S5. GL

@sshafranko do you know anything about the mic volume levels? I have increased mine as people seem to say i'm too quite (i talk softly on the phone) but i'm not sure if they are actually working or which ones actuall effect the in call volume as well as speakerphone mic volume. I notice there are two volume levels for some of the mics, an ADC2 and a DEC# volume. what is what there? Thanks!
