Guide to boost audio!

http://www.androidpit.com/how-to-manually-boost-android-mixer-volume. Great find! just edit existing "mixer path xml" file using es file explorer and save.. Works great for me!

Thanks man. Make sure to set permissions correctly.

there was an app for this on the nexus 5, so you dont have to edit it yourself. ill try it out on my n6. its called nexus 5 real volume boost.
---------- Post added at 04:04 PM ---------- Previous post was at 04:01 PM ----------
the app wont open on the n6.

does it seem to work pretty well?
tried viper but I honestly couldn't hear a difference on phone speakers or hear phones. possibly due to not being updated to LP yet

What are the correct permissions?

Thanks OP for the post. I hate to be “that guy" but one person responded to that article stating he wasn't able to update OTA b/c of those modified values. Just a heads up.

Comparing stock and the mixer path you provide, the headphones went from 20 to 30 and the speaker from 84 to 99, isn't that to much boost? Any risk to damage the speakers? Thanks

If Im not mistaken, that guide is for kitkat 4.4.4. Lollipop Mixer_paths appear different. Your file on Dropbox is correct, but I would unlink to that guide.
Editing the Headphone Path is not going to work. Here is the Lollipop headphone path
Code:
<path name="headphones">
<ctl name="SLIM RX1 MUX" value="AIF1_PB"/>
<ctl name="SLIM RX6 MUX" value="AIF2_PB"/>

RX1 and RX2 are the line out headphone volumes.
If Im wrong, please let me know but I edited this file on day 2 of having my Nexus 6 and its worked great.

Head phones are HPHL and HPHR values for both left and right channel so keep them the same.

I increased all those Rx values and speakers are slightly louder as well

How can one change the earpiece volume when your talking on the phone it needs to be a little bit louder

I increased those values with no difference. RX1 & 2 are the only values I've changed that worked.

I'm not a pro, but just changing all the 84 values to 99 worked awesome for me.... Hphl and hphr from 20 to 30 didn't hurt anything either.... Everything is extremely loud... Seems like es file explorer works all the time when manually editing that file versus using root explorer IMO!

So any way to boost speaker audio? All i've seen is headphone mod right?

Z2 mixer_paths

Could I get some help increasing external speaker loudness?
I'm already using the M8 sound mod and the quality is great and much better than stock, just trying to make the sound louder
searching I found changing the value = 75 to higher number would increase the sound but there is no effect.

[Mod] Stereo + Sound Boost for Lollipop (.242)

Note: This mod only works on Z1C & Thanks to @dontbelive & modified xml by @Lessismooore (http://forum.xda-developers.com/showpost.php?p=60209727&postcount=14)
Instructions:
Goto "system/etc/"
Backup mixer_path.xml
Move the newer mixer_path.xml and change the permissions to "644" (rw-r-r)
Reboot and Done!

I use the RU.242 Version and its not working

This mod kills audio, I get an Unfortunately Audio settings has stopped, I also can't get jetaudio and some other apps to run.
I removed the mod and everything works again

Now the Mod works but the sound on the headspeaker is not good.
It´s a effekt like the speaker overmodulate but didn´t stop if you turn down the volume.

Thanks for the mod, it's working but the sound is very distorted and the headphone is extremely loud that despite it may damage your headset, it can seriously cause some problems to your ears.
anyway I edited the original file "mixer_paths.xml" from the official lollipop in my z1 compact and adjusted the values for a high volume with clear sound without distortion...
I changed the values under these tags:

I agree with you, comparing to the other devices still low volume even after boosting it..
but comparing to its original sound I found this more better than never, and I am not going to say I am very satisfied but at least satisfied right now comparing to its real low original sound.
by the way I tried different values and when I tried to go higher or trying the mod in the OP, regardless the distortion of the sound in both experiences, when I play a song with maximum volume and touching the screen I felt like the screen is gonna explode because of the impact of the extreme high sound is somehow going into the device more than coming out of it, I don't know but maybe it's because of the waterproof thing this is why we're not getting the most out of the speakers.
If someone has any modifications, adjustments, additions will be more than welcome...
Thanks for sharing your feedback,

Tried only with earphones, sounds good..?

Here is stock lollipop mixer_part.XML I think stock speaker volume is louder than your mod. Analyze it if there would be another better way for mod.
In a nutshell.
Stock = loud speaker, low headphones volume .
Mod files = low speaker volume but loud headphones.

I agree with you, but i'm happy with this mod. Because i only hear music with headphones.
Great mod!

after using the mod for a while, i appreciate the increase of quality in headphones, but the speaker volume "croaks" a little bit.
i noticed that with the clear audio+ enabled, the quality is little better
do you have tried other combinations of the equalizer? Opinions?

Well, it didnt work.
Mine looks like this

<ctl value="RX1" name="RX3 MIX1 INP1"/>
<ctl value="Switch" name="LINE_OUT"/>
<ctl value="ENABLE" name="Lineout_1 amp"/>
</path>
Tried to modify it like ioneachmad suggested and only the earpiece was playing. Then I've modified like this
-<path name="speaker">
<ctl value="RX1" name="RX3 MIX1 INP1"/>
<ctl value="Switch" name="LINE_OUT"/>
<ctl value="ENABLE" name="Lineout_1 amp"/>
<ctl value="RX1" name="RX1 MIX1 INP1"/>
<ctl value="RX1" name="RDAC2 MUX"/>
<ctl value="POS_6_DB" name="EAR PA Gain"/>
<ctl value="Switch" name="EAR_S"/>
and only the speaker was playing, not the earpiece too.
Any suggestions?

Sorry for my terrible english, I hope you understand...

Give a blank line and will look like this
<path name="speaker">
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="LINE_OUT" value="Switch" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RDAC2 MUX" value="RX1" />
<ctl name="EAR PA Gain" value="POS_6_DB" />
<ctl name="EAR_S" value="Switch" />
</path>

It worked and it looks just like the last one posted by me..witch didnt work. )
Now, that I got your attention, can you sugget how to make it play louder? The volume that comes out of it its on the same level as in a phonecall and I know it can play louder than that. When I was on MIUI and tested the earpiece via CIT menu, it had some nice volume, not comparable to the bottom spekear, but non the less, you could hear it loud and clear.
If the value that I have to modify is "EAR PA Gain" value="POS_6_DB", i have already modified it into 7 (found it in 4 places in my xml).
LE: there is a cracking sound comming out of the earpiece (I think), even with the first "mod" - EAR PA Gain" value="POS_6_DB . On LOS14 is the same?

add this line <ctl name="RX1 Digital Volume" value="100" />
Code:
<path name="speaker">
<ctl name="RX3 MIX1 INP1" value="RX1" />
<ctl name="LINE_OUT" value="Switch" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RDAC2 MUX" value="RX1" />
[COLOR="red"]<ctl name="RX1 Digital Volume" value="100" />[/COLOR]
<ctl name="EAR PA Gain" value="POS_6_DB" />
<ctl name="EAR_S" value="Switch" />
</path>

Done it, volume seams to be the same and the cracking is still there, comming out from both speakers. (LE) : It appears when I exit an app which plays sound( ex. Youtube).
Another LE:
Comparing mixer_path from redmi note 4 to redmi 4, it seems that mine is missing these lines
<!-- These are the initial mixer settings -->
<ctl name="RX1 Digital Volume" value="XX" />
<ctl name="RX2 Digital Volume" value="XX" />
<ctl name="RX3 Digital Volume" value="XX" />
XX may be 84
Should I add it?

Cracking sound is a well-known bug in this device and still without an official patch made by Xiaomi, actually I really doubt that they will ever release such a thing.
But you can try one of the patches made by the community.

Can you share the fixed mixer_paths_mtp.xml to use stereo mod?

The mod is on 4pda. Check there for details.

Anyone have experience modifying mixer_paths_tasha.xml to increase headphone volume?

I'm working on modifying mixer_paths_tasha.xml to boost my earbuds volume and avoid having to use a volume boosting app. I'm using a set of AKG usb-c earbuds and they are not giving anywhere near the output on my PH-1 as the output on my pixel 2XL. So far I think I will need to modify the following 4 settings in 4 different path locations under /vendor/etc/mixer_paths_tasha.xml:
(these are all the stock values before any modifications)
<mixers>
<!-- These are the initial mixer settings-->"
<ctl name="RX1 Digital volume" value="84" />
<ctl name="RX2 Digital volume" value="84" />
<ctl name="HPHL Volume" value ="20" />
<ctl name="HPHR Volume" value ="20" />
<path name= "anc-headphones">
<ctl name="RX1 Digital volume" value="81" />
<ctl name="RX2 Digital volume" value="81" />
<ctl name="HPHL Volume" value ="20" />
<ctl name="HPHR Volume" value ="20" />
<path name= "voice-anc-headphones">
<ctl name="RX1 Digital volume" value="81" />
<ctl name="RX2 Digital volume" value="81" />
<ctl name="HPHL Volume" value ="20" />
<ctl name="HPHR Volume" value ="20" />
<path name= "voice-anc-fb-headphones">
<ctl name="RX1 Digital volume" value="81" />
<ctl name="RX2 Digital volume" value="81" />
<ctl name="HPHL Volume" value ="14" />
<ctl name="HPHR Volume" value ="14" />
What I am unsure of is what exactly the "initial settings" and different "paths" affect and why the volume value varies slightly between them. Anyone know if I do infact need to modify all 4 settings in all the listed locations to achieve a volume boost while using my earbuds and what values I should try switching to? I appreciate any and all help!

I found this thread https://forum.xda-developers.com/general/general/guide-technical-explanation-boost-t3202087 and it gives a nice explanation of the RX vs hph. However, it does not contain any explanation about the anc-headphones, voice-anc-headphones, or voice-anc-hp- headphones paths. I ended up increasing both RX and hph volume values for each path as well as the initial values but it does not produce a noticable effect.
