[REQ] [MOD] headphone volume boost?

I am not sure if i'm putting this in the right category but i figured since this is where the kernel development goes on it would be the best place.
I don't know about anyone else, but i use my phone as an all in one media device, and my main concern is the audio volume that comes out of the auxillary jack. I have tried 3 different ROMs and a few kernels including stock, and when my Inspire's media volume is maxed out playing through my car stereo it doesn't even come close to the volume output of my nexus s and captivate, much less my iPhone. The closest i have been able to get in better audio quality/volume comes from CM7, i am guessing because it is sourced off of AOSP. Even that is at least a notch or two under my cappy, and it makes a big difference.
I was wondering if there is anyway to make a kernel/ROM adjustment to boost the AUX volume output, NOT the phone external speaker.
Gladly willing to donate to a project for this.

Yes, please, I would love this, I use my phone to listen to music in my car and it's incredibly low, only when I turn my car's speakers to max is it at a normal volume... I would love this mod.

Download an app called volume boost.

Been there done that, it boosts the volume but outputs through AUX in mono. Doesnt work too well in my STEREO headphones or car STEREO

I know in CM7 that you can use DSP Manager to boost volume for just headset. Just increase the EQ evenly across the full range.

^^^ I recommend this as well. It works great.

I will try the dsp suggestion. I was just curious if we could figure out a solution for sense roms as well.

There has to be a better way to make this thing loud. I was irritated with how quiet my Rhodium was and this device is even worse. In Rhodium Land I procured a .cab that made my Rhodium obnoxiously loud at full volume. I want some of that.

Ah i remember the terrible audio on my TP2 all too well. Ahhh we need a headset boostt

To touch on the DSP resolution, it did not work. It boosted the power output yes, but distorted the clarity to an unusable extent.
Unfortunately a mod moved this thread because even though it is a development discussion, it seems they aren't enthusiastic enough to support this mod.
I'm offering at least 15$ for this fix..

Low Volume Output
I have just gotten a HTC Inspire 4G, and it's not hard to see that the volume output is doubtfully low compared to most other devices such as an iPhone. I have tried all the suggestions in this thread but none seem to work for a high volume output into a stereo,headphones,are any other jack devies. The EQ seemed to be a good idea I prefer to use my equalizer to sustain a better music experience. So overall I think there should be a mod or a tweak to increase volume output level.

A volume increase, or fix is definitely needed. This phone is too quiet.

There's a fix!
Root your phone and flash Revolution ROM v3.5. I just got back from cranking out Pandora on my car radio and the sound is great!

Check my sense Rom thread there is 2 beta kernels I just compiled with speed tweaks and volume boosts across both speakers and headphones(should in turn boost aux output levels as well). It's LOUD, to the point I can no longer listen to music at full volume. I still need to make some fine tuning adjustments, but I think I'm gonna try dsp manager to help even further. Some libs have to be replaced for dsp manager to work with sense roms, but with the sound boost alone, quality still seems to be pretty good with no distortion(that I heard anyway), and with this and dsp manager, it should be a pretty good fix.
I need feedback so I know what has to be fixed(or not fixed...too loud?, distortion?, etc)
Note these are froyo inspire kernels

It has to be whatever ROM you all are using... I took the exact same songs on CD -vs- my phone, and volume is the same, clean across the board.
No issues here at all.
Then again, I am VERY sensitive about my music and won't touch it unless it has a high bit rate. I also run volume leveling software on all of my music too. That way one song isn't terribly louder than the previous.

I'd really like this, my truck stereo isn't loud enough with the inspire at max volume. I don't want to change ROMs to fix this because every ROM other than what I'm running had some problem I couldn't stomach. However, while I briefly had CM7, it did boost the volume significantly.

Its already done as I posted. Flash the kernel from my (sense rom)thread(you'll have to search for it, but its there. Its stable, fast, and the volume is LOUD.(froyo kernel)

[Q] Speakers/Headphones Very Quiet

I'm wondering if anyone else is finding the audio output (be it by speaker or headphone), is very quiet? Whenever myself, or any of my friends go to watch a video or something on the Transformer, the first thing we do is try and turn up the volume even though its already at maximum. Even with a decent set of headphones (and I've tried multiple headphones), the audio is as loud as one would think.
I've done some searching through the forums, and tried to use this "Voodoo Sound Control", but it doesn't seem to give me many options. And when I tried the paid version, it said my device wasn't supported.
Anyways, I'm running Prime v1.9 with Netformer 1.6 kernel which i'm told has the Voodoo module in it.
Is there anything else I can try?

Yeah my headphone are pretty low but obly on certain videos same with the speakers. Try different videos and music see if there is a difderence.

Nah, it seems pretty universally quiet no matter what I play. Music from my google music account, local podcasts I download to it, youtube videos, ustream videos, etc.
Whether it be through the speakers or through headphones, its just really quiet. I have tried several different headphones I have, and its all pretty much the same volume. It has to be almost completely quiet in whatever room I'm in so I can hear it.
I was hoping this Voodoo stuff may help, but doesn't appear to be compatible (the thread says it supports TF 3.0 or 3.1 and not 3.2).
I'm out of ideas.

Voodoo works fine on 3.1 and 3.2

Yeah, sound on the TF is mediocre at best and horrible on headphones. I use an app called EQ and it really helps for the built-in speakers but headphones still suck. Not enough amp power to push decent sound.

I use THIS while using my earbuds. Greatly improves the performance of low-sensitivity headphones. Works like a charm and I have to turn the inline volume down to 1/4 on my earbuds. For some reason DVD movies are played back with low volume and this FiiO has done wonders with improving the volume and clarity even.

Voodoo control plus from the market is much better value for money, helps the devs in this forum and has truly amazing sound.
Using an external headphone amp like this is an ugly solution.

Unfortunately, that's not a feasable option for everybody. I own a B70 model TF as well as many others and I'm unable to gain ROOT so the FiiO is a better alternative than Voodoo control. Who's going to pay money for an app they can't even use unless your rooted.

[Q] which sound booster app do you use

i have seen several, tried them, am very underwhelmed with any of them, i use headphones and the Infuse is too quiet
Any suggestions?
currently using "Volume+" not good enough

voodoo control will get you 5db+ on the hardware end. if you don't have a voodoo kernel then get voodoo control plus which includes a module with the driver.
since voodoo sound works on a hardware level you might be able of use it with another audio booster app.
if. volume still doesn't blow you away then get more efficient headphones. some of the xeers headphones from Germany available on eBay have very high efficiency, only downfall of xeers headphones is the driver has flex so it may give a crinkling noise when you put them in after they break in. I have the td3 blacks and for rock music they are the best, not really an iem because they color the sound too much to qualify as a monitor but they are loud and sound great on music that you want to hear loud.

I use Voo Doo Control with Klipsch s4i's personally. Sound great.. got them because I once owned an iPod touch...Yeah........ But the play pause button works with the last media player that was added onto the device. Always works for pausing though. Just not always.. playing again. ): It works for ending calls and then the music starts back up that's nice. Sorry to make this more about the headphones than the app. But I agree with Dani. I like Voo Doo control. I like the options that it has for when you plug and unplug your headset. Like watching how loud the volume is. THAT IS DANDY.

Voodoo sound ftw
Froggys go ribbet

Voodoo Control definitely

Audio Quality

Appears awful when compared to my s5. Any Base makes vocal go almost to a pint you can't hear it and too much vocal results in tinny Base.
I've rooted and put v4a on the phone,but it's still awful with that too. Hoping a kernel with audio enhancements such as boeffla may make things better though?

you rooted S7E already?? WOW

I don't care about the audio quality of the noise coming out of that little noisemaker they call "speaker" but when I plug it in my car with the AUX cable, it seems to me so far that I have to fiddle with EQ much more than on my Note 5. The audio quality of LG Flex 2 was better than S5, Note 5 better than Flex 2, S7E... ? I don't know yet. Probably better than Flex 2 but it can't touch Note 5. IMHO
Note 5 has Wolfson chip AFAIK.What's in the S7E I don't know.

V4A? May i ask how did you managed to install it on a enforcing kernel?
Could you please provide steps...

How?

Guys, check the kernel and ROM forum. Root has been available since Saturday.
V4a works by flagging a zip file that makes changes to v4a to allow it to work with kernel selinux enforced set, then put v4a in compatible mode. It sounds awful though for some reason.
Would highly recommend using neutron from the play store as I found this produces far superior sound quality.

Oh I should mention root is only available for exynos version and not snapdragon.

I find the audio fine using the music player neutron and have setup soundalive and UHQ upscaler and tube amp pro.

Aux Cord Noise~?
I'd love to know if I am the only one experiencing problems with using an auxiliary jack cord?
It's littered with noise no matter what. Headphones sound great though...
I returned my first device thinking there was a physical problem with the port only to find the same problem in this one.
5 different auxiliary cables purchased and tested all poor quality only on this device.

Yes, same here. Switching on UHQ upscaler in sound setting fixes it. Sometimes, however, I have to toggle it off and on to get rid of the hissing noise.

I appreciate that, I'll have to try and let everyone know if that works.. I saw threads on other websites with no answers so really, thank you.
Seems rather odd even samsung support has no idea about this either.

But Samsung uhq upscaler work only with Samsung headphones (like level on wireless pro), so possibility of using this feature is limited

Identical issue for me as well. Thought I was going insane...tried three different aux cords and tried cleaning inputs in the car and on the phone. Headphones work fine. Toggling UHQ upscaler fixes the issue for me too. Very annoying....but glad I'm not the only one.

I am extremely disappointed with the S7 Edge's audio quality. First of all, the bundled earphones are bad and be it any file - FLAC UHQ 24 bit or an MP3, the sound pis very muddy. They fail to do justice to the lows and highs. Speaking for the device, my dad's Galaxy S5 sounds wonderful with heavy bass without compromising on the highs and the same goes with the Note 3. Samsung should have used a decent DAC and software to make the sound good for such a premium device. Even the low end Samsung devices have a good DAC.

There is nothing wrong with the DAC. It has a low noise floor and the frequency graph is almost completely flat. The headphone amp however is nothing to write home about. On the Exynos version you can at least edit the mixer.xml file to reduce the gimping Samsung did to the volume level to get a much louder sound without distortion. My RHA MA 750i have plenty of bass without the need to EQ etc.
Oh and the stock buds SUCK ASS

Definitely not a need to root BUT if you do, you can still use S Health and Knox with Helios ROM (Stock with optional mods).
They won't. They've gone with the "good enough" approach with the audio rather than wanting to be the best.

Headphones volume

Anyone else is struggling with SUPER LOW headphones volume? Before OP6 I had HTC One M8 which was LITERALLY 3 times louder. I am using SoundMagic E10c(cable, jack) and I am wondering if similiar problem exists for BT headphones. Need some way to have music with decent volume, since I am listening to music basically all the time.
Any way to fix this?

That's true. I hope that there will be a Sound mod in the future

My earphone volume is fine. Using non standard music player/ equaliser and good bearphones

I don't know why people say it's quiet on headphones I've 3.5 jack. I use bullets V2 from OnePlus and the volume and quality are fine.

I haven't noticed a difference in the sound over my LG HBS850 (Bluetooth), and I haven't tried my 3.5mm cable headphones yet.

I have OP6. After reading the complaints here checked with different brands of earphones. The sound is really loud and clear. Even at medium levels I have sufficient loudness. Equalizer too works well. I checked the earphone audio in Player Pro music player, Saavan streaming music and YouTube. I am very much happy with what I hear in terms of loudness and fidelity. I don't think the mentioned complaint is true universally.

I experienced the volume loss as well. When using the phone in my car I have to adjust the radio by almost 10 ticks (from volume 18-20 to up to 30 now).
Yesterday in my car with the oneplus 3 no problems, but the 6 has some very low volume settings. It's kinda frustrating at this point, the volume sucks and the quality doesn't match up to what the oneplus 3 could produce. I think it has something to do with the equalizer that oneplus 6 now offers. This morning while trying to adjust the settings I've downloaded the snapdragon equalizer on top of the baked in equalizer and that seems to kinda do the trick (boosts the volume by a bit).

Oh boy, same here. Using a pair of M50x's, they don't need much power to get going but I've noticed it's not as loud as my 3. I have a fiio K1 amp but didn't work on the 3, figured it might! work on the 6 but nope! so I guess I'm stuck using a amp with the headphone jack.
Oneplus really needs to improve their audio output power, that's for sure.

So I just noticed something. Music is actually fine and loud ONLY when i am choosing ringtone. Spotify/Google Play/VLC etc. all is silent, even after installing Viper4Android it's still to silent.

I agree, the volume of the headphone jack is very low and the overall sound quality is bad. My HTC one A9 is brilliant when using audio files from the jack. It's loud and clean but the OP6 is too low and very bad sounding. Not for audiophiles. I tried with Viper and it's the same.

I felt low volume intially , but after 5.1.8 update I think the volume is good. (May be its just my feel ?)
I tried with ATH M50x and samsung stock earphone.
With the filo e7K the sound quality is good enough ...

I have cheapo ear buds with 16 ohm impedance, just like yours. Anything above 80% volume is uncomfortably loud. Perhaps your unit is defective?

chiming in, no issue here, brand new, white OP6... I'm smitten

for me volume too low even with viper4android

Massively loud with black player, amp and good bass earphones, even the speaker is much louder than my HTC 10

Give ElementalX kernel a try, I've flashed it and boosted my amp output. It helps! with viper4android I don't really need an external amp anymore. But.. it's still better
