New with 4.2.1 update -
Equalizer REDUCES volume of audio to all outputs on Galaxy Nexus

To reproduce:
Play music, enable equalizer, no matter what settings are selected, audio level is reduced and sounds bad. Even with all equalizer bands set to +15 (max), the audio level is still below that with no equalizer enabled.

OR - use any Play store app that controls equalizer, or even more specifically, because of low volumes with GNex, I have been using the App 'Speaker Boost' which is simple small app that enables audio boost for all audio sources. With 4.2.1 and GNex, this app actually reduces output instead of boosting it.

Prior to 4.2.1, with 4.2 and prior JB releases, with equalizer enabled, audio levels could be boosted. Not any more.

Dec 10, 2012
Same thing here... (Nexus 7 on 4.2.1). I originally thought my equalizer app stopped working so I uninstalled/reinstalled and still no audio boost. Prior to recent Jelly Bean updates equalizer gave me a decent and needed audio boost.
Next I tried 2 other equalizer/speaker boost apps... no effect... which really sucks because the Nexus 7 really needs a speaker boost for watching video, etc.
Dec 11, 2012
Does Google care or even read the comments on the horrendous sound problems? I really like JB on my Samsung Nexus, but the sound issue sucks, so many complaints so little response
Dec 11, 2012
I hope Google does read these comments because the audio sound now needs an enormous boost just to produce an adequate level of sound. SpeakerBoost does very little now to help which is a shame
Dec 12, 2012
Please get this sorted Google, I just shelled out for 2 nexus 7 tabs so my parents can video chat with their grand children and there's next to zero audio coming from the speakers, same with movies. Huge let down on otherwise great hardware.
Dec 12, 2012
Yes. Im in the same boat here. Bought new headphones and the sounds volume is terrible i payed 250$ for earphones to get such a low volume. And yes it happened like after the update 4.2.1. Please Google take a look at this and fix the problem.
Dec 12, 2012
Yes this is a major problem for me as well. Seriously this is one of the reasons I have a smart phone. My music sucks now. My Nexus 7 and my Galaxy Nexus both have this problem since 4.2.1 
Dec 14, 2012
the audio issues on nexus 7 & 4.2.1 are 'hanging offenses'.  just unforgivable guys - how on earth can a billion dollar enterprise NOT have effect process controls in play?
HORRIBLE.  try to watch a movie with MX Player and see what you hear, absent running it to an amplifier!  try any of the vain attempts on the Playstore to 'boost volume' or EQ enhance ... they don't work with 4.2.1.  horrid.  why do you think people buy this device?  to hack on?
Dec 17, 2012
I have 3 galaxy nexuses (or nexi) in my home and all have this problem. I run Cyanogenmod on 2 to try and fix this issue and they did up until this last upgrade.
Dec 29, 2012
My nexus 7 volume is rubbish and to boot the problem brought up in first post  about equaliser making it quiet is exactly  rigHt
Jan 3, 2013
I  tried speaker boost app but this made lower at full boost & higher at no boost what's the answer?
Jan 3, 2013

Today bought nexus 7 and after unpacking and configuring WiFi it notified of 4.2.1 update. Stock was 4.2. Audio was OK before update. After upgrade completed and reboot done the sound stopped working. Both speakers and headphones.

Went back to the store and the replaced it for another unit no problem. This unit is on stock 4.2 and I don't intend to upgrade till I find a solution.
Jan 8, 2013
Instead of listing the complaints here go over to Google + for larry Page, 
Sergey Brin and Eric E. Schmid, and post your complaints on any of their posts, an then maybe if you are lucky and if they read what we write, or they feel embarrassed that we had to go to their social page to get an answer, they will light a fire under someone so that they at least answer our concerns,  and if we are extremely lucky fix the problem.
Jan 14, 2013
I have a GSM Galaxy Nexus and a Nexus 10 with 4.2.1 on both. The equalizers seem to input the opposite affect. I've tried a few sound apps and nothing is helping. I moved from iOS to Android and while I'm enjoying everything else, the poor music quality I'm hearing needs to be corrected. Sounds like a software update issue.
Jan 21, 2013
None of the Apps recommended on Nexus user sites to increase volume on Nexus 7 since 'upgrade' to JB 4.2.1--Music Volume EQ, Speaker Boost, or Volume Control +--has worked.  This is extremely irritating.  What, besides the fanciful suggestion to Goggle + Page/Schmid/Brin, is the best way to register this complaint with Google and see any improvement? 
Jan 21, 2013
I am using PowerAmp for my media and it has resolved the volume and equalizer issue.
Jan 21, 2013
Sorry I don't understand, what is the stock music app and how do I access

I tried 3 downloaded Apps, one after the other, Music Volume EQ, Speaker
Boost, and Volume Control+.  None worked and it seemed like at least one
DECREASED the volume.

Thanks for the reply.

The stock music app is the music or audio playing app that Google includes with the device.  I assume there is one.
Jan 24, 2013
probably a good idea to root the tablet and remove the stock player altogether. install a good player from the store, and noozoxide, which is fabulous.  
Jan 29, 2013
Hi Guys, 

I have problem with Samsung Galaxy Nexus 3. Every time when I am taking off my earphones the equaliser simply doesnt work. In case I want to plug in earphones back and use also equaliser I have to restart my phone and after it works again. 

Why ? 


Jan 31, 2013
I am getting some serious crackling and popping when I play music using Android 4.2.1. IS this common? If so, I hope they fix it. I can't believe they missed this! Do they not test everything???
Jan 31, 2013
#22 arpruss
Has anyone had a look at the changes in the equalizer and sound effects pipeline source code to see why things changed?
Feb 5, 2013
I have the same problem of very low volume sound from speakers on my Google Nexus 7 tablet running Jelly Bean 4.2.1. Can Google fix it with an update patch?
Feb 9, 2013
Already had an iPad before i bought the Nexus 7 and I will probably go back to Apple if Google does not solve problems like these...
Feb 9, 2013
#25 arpruss
In defense of Google, it could be that they found that boosting the audio resulted in speaker damage and so they disabled the possibility.

If that is the case, I think they should tell us that, so at least I can buy a device from another supplier in the future. There are endless reports of this and not a single comment from Google.

#27 arpruss
Does anybody know if this problem is present in 4.2?  The changes between 4.2 and 4.2.1 were very small and didn't seem to touch the audio code:
Feb 11, 2013
I have a fix: (unfortunately only for rooted devices)
You need to go to /data/app and find your equalizer app, then cut and paste it in system/app and rename it to its name (I'm using musicfx, so I renamed it from com.something yo musicfx), reboot and it should work
Feb 12, 2013
#29 arpruss
Very interesting.  Do you know what's going on?  I looked at the 4.2.1 source, and the MODIFY_AUDIO_SETTINGS permission is not locked up.  Is there some other system-only permission that is needed for the equalizer?

It might be possible to make a "normal" root app (i.e., one that doesn't need to be installed in the system image--modifying the system image can be risky) that gets around this.  I don't have (or want to have) a 4.2.1 device, but if somebody wants to test root-only SpeakerBoost code for me, email me.  (Click on my username for my email address.)  It may be a while before I get back to you.  I have other projects.
Feb 19, 2013
Nexus 7 upgraded to 4.2.2.  Downloaded Volume Control+ from Play Store.  Problem immediately solved.
Feb 19, 2013
For #30. Thanks for the tip. I also installed Volume Control+ on my upgraded Nexus 7 and Nexus 4 devices, but I can't find any settings for boosting the volume. To me this application just looks like a new frontend to the normal volume control. 

How did you manage to boost the volume with this app?
Feb 19, 2013
for #30 

Thanks for your suggestion. But unfortunately i cant find anything different with installing and without installing..... 

Samsung Galaxy Nexus 4.2.2
Mar 1, 2013
Same problem on 4.2.2 after upgrading I noticed a big difference in volume and if u go into the equalizer and turn it over 0db or under 0db it gets lower volume. On 4.1.2 it was go and had no problems
Mar 1, 2013
I have a nexus 7 32gb
Mar 30, 2013
#28 - that didn't work for me though I'm using a program named Equalizer.
Apr 3, 2013
Facing similar problem ......... if u go into the equalizer and turn it over 0db it reduces the volume. equalizer at 0db or turned off gives maximum volume.
come on ... pls help.
Apr 29, 2013
Same issue with the Verizon Nexus, EQ worked fine until 4.2.2 now anything above or below 0 db cuts the volume drastically so none of the standard EQ settings can be used or custom. Not so worried about the volume but would like to be able to have back my custom EQ setting.
May 5, 2013
I just brought a asus nexus 7 Friday with 4.2.2 and I'm having the same problem. Google I love you but you must fix this volume problem or you are going to lose a lot of faithful customers including myself. Please fix very, very soon
May 20, 2013
I just bought a Nexus 4, and after a few days I used it, the speaker volume is almost imperceptible. I've tried volume+, speaker boost and the problem didn't solve. Anyone has solved it??
May 23, 2013
I use class for boosting volume in my application.
Now I see that if system volume level is middle, then Equalizer class works fine (I set maximum level for each bend).
If I start to increase system volume then effect of Equalizer is proportionally decreased. So summary volume leve stay the same.

The same effect you can see in Google Play Music application.
Jun 14, 2013
Same issue here using AOKP on a Sony Xperia ZL. This doesn't make any sense to me. It really seems like Google is trying to kill Android, but why would they? What kind of crazy psychological experiment is this? JB is a really nice system, but no USB mass storage and unbearably low volume just makes me regret my decision to shell out for a top-level Android device. 
Jun 22, 2013
Galaxy S3, same issue, come on Google. 
Jun 25, 2013
Same problems here. Since I have the S4 (and thus Jellybean) equalizer doesn't work anymore. Pretty lame, because it is one of the best apps out there.
Jun 26, 2013
#44 arpruss
I just had a user of my Earpiece app report something interesting.  Apparently if you raise the boost high (presumably while sound is playing), for about a second it plays at the higher volume, and then goes back down.  Earpiece uses the Equalizer class like most of the other boost apps.

Does anybody else see this behavior: Turn on boost, e.g., in Speaker Boost, and there is a boost effect, and then it goes back down?  If there is some initial boost, one could see if there is a way of maintaining it.

Has any developer looked carefully at the source to see what the change between 4.2 and 4.2.1 is that did this?
Jul 17, 2013
Same problem here, even with stock (MusicFX) equalizer on Galaxy S4. Seems as though something significant changed in the Equalizer class code rendering it essentially worthless to all apps utilizing it. Not only is this an Android customer issue but think of all the app developers out there utilizing this code, which does not work for a population of customers that is growing everyday. Most customers will blame the app and it's developer, thus more negative reviews and a negative impact on future sales. How can an issue this rampant be completely unacknowledged and unaddressed? Especially given the significance of audio quality and sound level of today's consumer. Google, please at least acknowledge the issue. 
Jul 31, 2013
Samsung SII Android 4.1.2 the same problem.  Very unhappy with the latest update.  I will buy me an iPod for the sound quality that provides. Shame for Android!!! 
Aug 1, 2013
Yesterday received upgrade Android to 4.3.
Nothing changed bug still exist...
Aug 2, 2013
Ditto with Galaxy Nexus and stock JB 4.2.1.  It's disappointing to read 4.3 isn't better.  I agree with #12 "go over to Google + for larry Page, 
Sergey Brin and Eric E. Schmid, and post your complaints on any of their posts"  and hope lots of people hit them up over and over.
Aug 19, 2013
My GNexus (Android 4.3 stock rom unrooted) was alright, but after running voulme boost, the sound became low. Now during talk with speaker on, I am not being listened on the other side, though I am listening the other side clearly. Please suggest.
Aug 19, 2013
#52 arpruss
Try just removing your volume boost and rebooting.
Aug 21, 2013
I wondered what happened to the sound today when playing music from my Galaxy S III, thru Bluetooth in my 2013 Charger! Had not been driving Charger in a while, but when I did, music sounded awesome then today it was horrible! Was embarrassed to even turn it up! I just bought over $200 bux in albums on Google Play Music & have subscription for $9.99 a month! This must be fixed!  Its awful when u use ur phone for mostly music & then this happens on an update! 

Aug 26, 2013
the same issue here after updating my galaxy s3. noticed that Play Music provided by Google has EQ works just fine, but no third party apllications such as Music Volume EQ other apps. 
Aug 28, 2013
I just noticed that this issue began in Early December of 2012. We are now almost 9 months into this issue, and I would not have even known about it, if I had not purchased the Google Music Monthly Deal, and jujst began using Google Play Music, because I am now driving a 2013 Charger that can take my Bluetooth and Play my music from my phone. I HATE radio music, so I set up all these playlists and PAID FOR A LOT OF MUSIC recently, and as I said above, one day it sounded amazing, then a few days later after an update, and I don't know which update, because y'all above starting in December are talking about one update and I am talking about an update I received OTA about 2 weeks before I began really getting into Google Play Music. I wish there was a way to know when I received my last update on my Galaxy S 3, last and which of those numbers y'all are talking about that it was. I have been with T-Mobile for over 12 years and was on the list for the very first "smart-phone" the G1, nine years ago when they first came out, so even tho I have been an Android Girl for that long, I still am not as incredibly knowledgeable as most of you all are. I installed the "Equalizer" by Smart Android Apps and purchased the "Unlock Key" for a better app..I don't know, I thought it would make it a better app. The free version had the most downloads and very high rating compared to all of the others. Should I un-install the app and just use the equalizer FX? IS ANYTHING GETTING DONE? 
Aug 30, 2013
Sorry Lass, Android Developers can't hear you :(

What kills me is that I'm on 4.1.2 and heard that 4.3 is still having the same issue unsolved. It means that I'm gonna suffer alot to get this solved, Samsung and Google simply i loathe you.
Sep 2, 2013
Same Here ..!! Nexus 4 with android 4.3 latest update...Still having same problem..!! :( :(
Sep 24, 2013
We have the volume reduction issue with an ME370T Nexus 7 tablet and 4.3 (also had it with 4.2).  Specifically, when our code uses and sets any of the frequency bands off the normal midpoint (which is 0 in our case) we get a volume reduction.  Even if we increase all the bands to the maximum it only approaches the volume level when all the bands are at 0.  It still seems to be doing equalization but the volume is quite a bit lower and makes the equalizer basically unusable.  Setting the bands back to 0 restores the volume.  We are really searching for workarounds.  It does seem to be an OS issue.  Any responses from Google?
Sep 25, 2013
Rocket Player has the Equaliser working properly with no issues at all on my Galaxy S3, whereas others do not work !!!! did the Rocket Player do any sort of magic here if it was an OS issue? Google, Chop Chop..!!! sort it out or i'll do something. 
Sep 25, 2013
#60 arpruss
Here's a hypothesis. While the OS allows equalization between bands, it enforces an absolute total limit on all the bands, so if you raise one band, the others go down. And it misimplements the limit...

I am busy with other projects, but I really think somebody should carefully go through a diff between the source of the last OS version without the issue and the source of the first OS version that has the issue.

agmobile: Are you using audio stream 0 (global) or an audio stream specific to your app?
Sep 26, 2013
arpruss: We're using our own, that is, the session ID of the AudioTrack we're using to play our audio frames.
Sep 26, 2013
Also, one thing about that hypothesis arpruss is that we see the overall volume reduction even if we reduce one of the bands slightly.
Oct 13, 2013
#63 arpruss
I found where the code was added.  It's obviously quite deliberate:
Oct 13, 2013
#64 arpruss
A risky thing to try on a rooted device where you have a good recovery console and aren't worried about bricking might be to replace /system/lib/soundfx/ with a custom build that removes the gain limiting code (or maybe with a previous Android version--the change was introduced in 4.2_r1, so 4.1.2_r2 might work).  At your own risk of course!
Oct 15, 2013
Nice research arpruss.  I wonder though why we only see this behavior on some devices.  I wonder if the band level they're using in the comparison is not high enough on some devices but is on others.
Oct 15, 2013
#66 arpruss
There is a subsequent patch that replaced the very simple volume limiting system of the patch I posted about with a much more sophisticated one:

Maybe the differences users are seeing are due to different behavior of the two patches?

Or maybe some vendors have customized the effects library?
Oct 18, 2013
Someone could write this Eric Laurent person at Google who made the change, with a link to this thread. Perhaps that will move things along slightly. My Nexus 7 is hopeless on an airplane without perhaps noise canceling headphones.
Oct 19, 2013
If anyone cares to contact the author who made this change, it looks like the address is I would do it myself, but unfortunately I don't have the technical knowledge required to describe the problem.

Volume sucks on nexus 7.

#70 johnnyrenoNV
Dang I hate this pieced together linux-based pile of horrendous rubbish.  No more android ever ever EVER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!suckitulazypricks
Nov 6, 2013
I've been doing some tinkering with the effectsbundle.cpp and I just added a modifier to the max gain. If you felt inclined to bypass the limiter entirely you can just comment out the line where it sets the active volume control parameter to the gain corrected volume.  

#44, the reason there is a noticeable ramp in the volume is that when the gain correction is hit in the EqualizerLimitBandLevels function, it hits the volume smoothing function to try to avoid pops and clicks.  

I built a 4.2.2 AOSP for a Samsung Galaxy and it seems to be fine with the volume now, after I bypassed the gain correction.  While you're poking around in there go ahead and add a few extra bands in the MAX_BANDS. I think 6 bands is a decent starting point, and most EQ apps follow the demo app where it pulls the MAX_BANDS instead of hard coding 5, so there shouldn't be any issues with most EQ apps.    

My main issue with Android right now is that I can't seem to get global effects on any player that uses web view or NDK with my Galaxy.  Which I find strange since my Galaxy S4 has no problems with global effects on players that use web view or NDK.  I wish I could see the audioflinger for the S4.  It also might just be that I flubbed something up when I altered the audioflinger for my AOSP build but I find it easier to blame Google instead of debugging my code.  
Nov 6, 2013
I think I rec'd this in error.

Nov 11, 2013
I wonder have google acknowledged this bug yet, and if they have any plans to fix.
Nov 11, 2013
Why would Google care with the Nexus 5 out and Galaxy Nexus no longer
getting updates?
Nov 11, 2013
I think I've got an workaround. It seems it works on some phones such as Galaxy S2, Optimus G pro of Jelly Bean.
I was developing the mp3 player app which supports gapless playback.
To support gapless playback, I created 2 MediaPlayer objects and Equalizer objects accordingly. When I played them simultaneously, the first one faced the same problem which reduced the volume when the equalizer was on.
But weirdly, the second one didn't have the problem and it sounded well.
So I created the dummy MediaPlayer object before the real MediaPlayer object which was to play the songs.
And also I needed to call the prepare(), start() and stop() method of the dummy one.
Hope this would help and wonder if it works for you.
(I had a headache for several months due to this issue, too.)

If you'd like to test my app, you can find it below.
Nov 11, 2013
#76 arpruss
Very clever, though I don't see from the OS source code how that would work.  

Would be good to see if this can be tested with some other devices.  Have you experimented to see if you need both equalizer objects, or if it's enough to have one for the second mediaplayer?
Nov 11, 2013
Thanks for the comment, arpruss.

It's enough to have one for the second mediaplayer.
And I needed to hold the reference of the dummy one during the playback so as not to be killed by garbage collector.
Nov 12, 2013
#79 arpruss
Did you have to attach some data source to the first mediaplayer?
Nov 12, 2013
Installed on Galaxy S3, didn't notice any difference. 
Nov 12, 2013
arpruss, yes I did. To call prepare(), you should attach some data source.

Below is the pseudo code I wrote.

// create dummy player
if (android.os.Build.VERSION.SDK_INT >= 14) {	// 4.0 ICS+
	if (!mJunkPlayerStarted || mJunkPlayer == null) {
		mJunkPlayer = new MediaPlayer();
		mJunkPlayer.setDataSource(getApplicationContext(), mCurrentItem.getURI());
		mJunkPlayerStarted = true;

// create real player
mCurrentPlayer = new MediaPlayer();

// create Equalizer for mCurrentPlayer
mEqSettings = new Equalizer.Settings("Equalizer;curPreset=-1;numBands=5;band1Level=600;band2Level=0;band3Level=0;band4Level=0;band5Level=1300");
mCurrentEqualizer = new Equalizer(10, mCurrentPlayer.getAudioSessionId());

// prepare data source & play song
mCurrentPlayer.setDataSource(getApplicationContext(), mCurrentItem.getURI());

Dear malnoshan, thank you for the test. I'll also test on Galaxy S3 once I have a chance.

FYI, I've also tested it on the Android emulator of Jelly Bean and it worked.
Nov 12, 2013
#82 arpruss
OK, I have three versions available to try:

To try these, first run SpeakerBoost, set a boost, and then run your preferred media player.

The difference is that SpeakerBoost's sound effects are global, so I don't know if the trick will work.  The three versions of the apk try three versions of the trick.  The first version is the one above--start a dummy player, stop it, but don't kill it.  The second version is the same but it doesn't stop the dummy player--just lets it play to the end (it's just a beep).  The third version tries a different tack--it restarts the equalizer every second or so.  Some users in the thread reported that the boost works initially and then stops.  The hope is that this method will keep the equalizer going.

I'd appreciate any test reports.  I don't have much luck getting sound running on an emulator.
Nov 12, 2013
Sorry to report I tried all 3 versions of the test speaker boost on the
nexus 5 (stock kit Kat 4.4) bit none of them provide any increase in
Nov 12, 2013
I've tested the three versions of SpeakerBoost with Google Play Music on my Galaxy S2.
Well, it didn't work. Even though I moved the thumb of the seekbar, the sound didn't change immediately.
But in a few seconds(10 secs), the sounds got a little bit louder, however not every time.

BTW, the global effects doesn't look like it works.

Later, I'll provide a test apk which doesn't use the global audio effects.
Nov 13, 2013
#85 arpruss
That's too bad.  Did you guys first run SpeakerBoost, set the boost, and then run the media player?
Nov 13, 2013
Yes, I did as you instructed.

Arpruss, does it work on your device?
Nov 13, 2013
I also did as Arpruss suggests.

I also installed the Gapless Audio Playback with similar EQ results on the
Nexus 5 -> that is, the loudest the music gets is with EQ off, or with EQ
set at flat, once any EQ settings are applied, the audio level drops. I do
like the player tho <g>
Nov 13, 2013

Gapless: I don't have a 4.2+ device to try on.  I did try on the Genymotion emulator and it didn't do anything, but I don't know how accurate the emulator is.
Nov 14, 2013
rgam808: You installed the gapless player app and got the same EQ results on Nexus 5? That's painful. Then, I need to find another workaround or adopt the native EQ library.
Nov 14, 2013
arpruss: well, I had found the same problem with the 4.2 emulator and it had worked well after I'd created the dummy player.
Anyway, I need to test more and will get back to you.
Nov 14, 2013
I have a Galaxy Note 2 N7105 (t0lte) with carbon Rom JB4.3, and the SpeakerBoost app works fine all the time.  Does anyone want me to try anything to understand the differences between my Android build and the Nexus build that is exhibiting this equaliser issue?  Btw I can also increase the volume in dap manager by turning up all bands and it works equally well apart from adding some distortion.
Nov 25, 2013
Now I've got a Nexus5(Android 4.4).
I can hardly see the volume reduction problem on this device.
Especially, when I level up the highest frequency band of the equalizer to the max, it doesn't reduce the volume at all.
A very little bit, when I turn on the bass boost and increase its strength, it decrease the volume. But it's difficult to recognize.

Hope to hear whether others see the volume reduction problem on Android 4.4.

Samsung musicplyer  with no work

Jan 30, 2014
I just upgraded to a Galaxy S4 and am bitterly disappointed that I can't get any equalizer app (including the stock Music Fx) to work on 4.3. My old DROID global sounded better! I have premium subscriptions to things like Spotify that now sound like am radio through my head phones. This Needs to be fixed Google. Especially if you are trying to get subscribers to Google Music.Thank you.

Feb 13, 2014
I just installed the Android 4.2.2 Jellybean update on my Samsung Galaxy S3 and ran into the same issue with this equalizer app. It fades out ALL sound outputs on my phone, including my notification, media (music, video, etc.) & ringtone volume and makes it sound horrible. When I play music on Google Play Music, even with headphones, it comes out very faded and horrible sounding. This all occurs whether I have the equalizer powered on or not. I uninstalled this equalizer app & this solves all my sound issues. This was not an issue, unfortunately, until I installed the 4.2.2 update last night. Way to go, Google!!!
Feb 27, 2014
Unfortunately we still have this issue,which is a pity because google music used to sound good. I tried poweramp equalizer and that seems to work quite well on 4.3

Don't know if google will fix it. It's gone on a long time.
May 12, 2014
Still happening on S3 with 4.4. How do we get the priority up from Medium?
May 12, 2014
#99 arpruss
I doubt that Google considers it a bug.  Rather, they may look at it as prevention of overdriving of speakers.  Probably our best hope at this point is to encourage people who make alternate ROMs, like CM, to roll this back.

As the equalizer is non-functional at this point I don't know how it can be considered anything other than a bug.

I just got a Lenovo A850+ about a week ago. It's running Android 4.2.2, installed noozxoide, got the same issue. Stumbled upon this site, Just install the aptoide app. After the installation, run the aptoide app. This is like another market type app. Within the app, search for the app Volume Booster. My phone now sounds slightly louder now. The volume boost affects the plugged in ear phones, Bluetooth ear phones and the built-in speakers. So I suggest give it a try, it might solve your the problem.

So annoying!  I want to watch Dexter in the shower with my Bluetooth speakers on my Nexus 5 in a zip lock bag, but it's not loud enough, lol.  Please fix!

Just got a brand new 4.3 phone with a Tegra 4i chip ... and sadly after hours of searching I found out this issue.
Anyone tried to contact the dev of the code that produce this behaviour ?
btw I tried your apps arpruss, and I have:
- error please try to reboot
- when I change the gain the volume does not increase or decrease but it looks like some frequencies are droped out

Any hope to get some general code tweak that we could give to people working on specific custom ROM ?

Using Rocketfish RF-MAB2 BT headphones with Motorola Droid Maxx running Android 4.4.x. Unfortunately, applying boost on any of the EQ bands results in unexpected overall (RMS) volume level drop. Volume bug mentioned in the app description must be affecting more than just Jellybean. Bass booster works fine with no volume drop.

I managed to root my android and install Viper4 android for 4.3.
The sound is now MUCH MORE louder, so it solve my problem (well Viper4 android is crashing for time to time, but that's not the same issue^^ )

I haven't done anything with Cydia Substrate myself, but it seems to me that it shouldn't be hard to use it to disable the effects of these patches.

How about its about time EQUALIZER did something about it?! They're hiding around Google? The app does not work and they could have done something OR, advise customers the APP DOES NOT WORK BEYOND IT'S! Right now, EQUALIZER is hiding that info in the details.
