[Q] How do I increase Bluetooth volume?

The overall volume on the Nexus 5 (and every Android phone I have had) is very low. I even just rooted my phone to adjust the volumes in "mixer_paths.xml" only to realize that I can only adjust headphone and speaker volumes there.
Is there a way to increase all media volume, or at least Bluetooth volume?
With almost everything I play on my Nexus 5, I have to set the volume at about 90% to get the volume right. That leaves no range if I need to increase it when something was recorded at a low volume. I would like to make it so that a normal volume setting is more in the 50% range.

Install Viper4Android sound mod from here: http://www.mediafire.com/download/cz6l67mk81zsyq4/ViPER4Android_FX_v2330.zip
It increases the sounds system wide! If the normal apk install doesn't increase the system sounds, then push the apk in /system/priv-app/, fix permissions and reboot. It will surely work now

I found Viper4Android mentioned in other postings, but I am not fond of installing random packages off the Internet. Is there some way of verifying what that does before I install it?

I can assure you that v4a isn't some random mod floating around the internet. I've been using it since ages and it works perfectly.
If you want to know more about the same, you can follow this official v4a thread: http://forum.xda-developers.com/showthread.php?t=2191223
If you aren't satisfied with the official thread, then you can even follow the V4A discussion thread in the Nexus 5 apps forum: http://forum.xda-developers.com/google-nexus-5/themes-apps/viper4android-t2543796

I'll be that guy.
Questions go in the Q+A forum, not general. Normally I'd answer your question at this point, but there's no need. Next time use Q+A. That's what it's there for.

Another V4A user here.
I wouldn't flash anything I don't trust either, but you have nothing to worry about with Viper.

You can also normalize those media files to the same volume as your other files. Easy to do if you're converting them yourself already.

I listen to things on BeyondPod and I haven't seen that they have any function for normalizing the audio. It would be nice since the podcasts seem to vary in volume. Actually, I guess that BeyondPod is the worst for having low volume. Pandora seems to vary in volume, but I don't usually have to set the volume to 100% to hear things.

Viper4android works
Sorry about posting to general. I don't know why I didn't notice there was a q&a section. I will know better next time.
I downloaded the source for viper4android from github and built it myself. Not that I went over every line of code before installing, but at least I know I made the apk.
https://github.com/vipersaudio/viper4android_xhifi
And it seems to work! At least for headphones so far, but I will try bluetooth. It is much, much more complicated than I was wanting, but I guess if it changes the gain, then that is great.

It's great for wired headphones. I don't see it being able to do much with Bluetooth volume though. Unlike every other volume, bt isn't kernel managed. It's managed in the bt stack. Unless viper does something special that I'm not aware of

It looks like the Viper volume gain adjustment does work with Bluetooth media as well on my Nexus 5, so things are working for me.

Works great for me too. I also followed the above G4 guide. Unsure of battery drain at the moment.

I have been using this for more than a month and no battery drain issues or any other problem. Works perfectly. And yes I had followed the same G4 guide.

Phone Speaker profile + Surround sound!
I made a V4A profile after installing the Surround sound mixer_paths.xml found here: http://forum.xda-developers.com/g-flex2/development/surround-mode-h955-t3376881/ (also edited volumes in post 3 of that thread.)
After installing V4A, go to Menu > UI Setting > select "Expert"
On the Phone Speaker tab:
Enable V4A-SpeakerFX
Enable FIREqualizer > Preset "Treble Booster"
Enable Convolver > Impulse Response "SonicHunter Speakers.wav" (Download it here, unzip and copy the .wav file to sdcard/ViPER4Android/Kernel/ folder on your phone. Credit to Vinardo_ZzZ 2000 and his awesome V4A IRS thread here)
Enable eXtra-Loud > Moderate > 6x > -6.0 dB
Output Gain 4.1 dB
Limit Threshold -3.0 dB
You may need to tweak the dB values according to content, but this particular V4A convolver combined with the surround sound mod has made for a pleasant stereo experience for me. Hope others will like it too.
I also suggest trying out Viper4713's Material mod for V4A 2.4.0.1 found here. Makes the app look that much cleaner.

@PhantasmRezound tried your settings but my earpiece speakers still distorts a lot. Better than original surround mod but still far from an enjoyable result. I think flex 2 earpiece can't be pushed to high volume. Thanks anyway

There is always a possibility for slight variance in hardware (aged speaker/phone case altering sound) but especially source material plays a part too. I was listening to a lot of music and movies just fine without extreme distortion... then certain YouTube videos that had clipping from poor gain and low voice tone distorted the earpiece for me too.
You can try to redo the surround values even lower, maintaining a difference of about 8 between the the speaker channels to maintain stereo balance. You may also use V4A from here and alter the last three gain values until the distortion is gone. For one video with clipping I watched, I had to drop eXtra-Loud to -10.5 dB and Limit Threshold to -6.0 dB to eliminate the clipping causing distortion, then reboost the Output Gain positive step by step until volume was higher again, without distortion.
Going to experiment with the high-pass filters and possibly other Qualcomm biquad filters in the mixer_paths.xml file next.

Same, anyone know how to solve this?

Make sure you are rooted successfully and your SU manager app is allowing root to those programs (using Chainfire's SuperSU here.) Ensure Busybox is installed and running properly (using Stericson's Busybox Free here.) SELinuxModeChanger should have Permissive pressed in/greyed out; reboot for it to take effect first time. Verify Permissive system in the system Settings > General > About Phone > Software. Make sure you're using the latest version of V4A compatible with LP (2.4.0.1 at this time.) Install V4A drivers from its menu and reboot; check Driver Status and it should read "Normal." If it doesn't, something above is broken or perhaps another audio mod may be conflicting (if you installed other full system EQ style mods, not stereo/boosted speaker simple mods typically.) If Driver Status is greyed out on the V4A menu you need to change FX Compatible mode to Normal. (Compatible mode isn't system-wide effect and only to use with certain audio apps like Poweramp that run EQ functions of their own alongside V4A.) Good luck and hope you can trace the issue down.

Thanks a lot. I got it working. What audio source are you using to test it?

Stock 5.0 and Viper4Android

Hey guys.
I have been avoiding stock ROM primarily because of the fact that I couldn't use V4A on it.
I would install V4A(after disabling JBL or not,no difference at all),and I would lose audio and the floating audio control window which would appear whenever I would click the volume buttons wouldn't show at all(I tried changing the volume levels from Settings too,but it did nothing)
So,if anyone has V4A fully working on stock 5.0,can he/she be so kind and share the procedure they followed when they were installing V4A?

[ROOT][MOD] Xperia X Performance Volume Boost for stock config

What's bugging me about my brand new Xperia X? The overall low volume.
These simple tweaks, this mod if you may, simply modifies a few lines from the stock audio config files which, after a reboot make your speakers louder and headphones, a bit too loud (but I didn't hear anyone complaining about Xperias for being too loud lol)!
It's for rooted users only and for me it sounds a lot better than using (possibly) unstable sound mods instead of simply adjusting the volume on some pretty decent stock drivers.
***Tested on X Performance running Nougat. I've also got my hands on Xperia X Performance files which are pretty straight FWD see attach. Thanks @bkk99213 for testing and for the file!***​​​
Make a backup first or if you didn't simply put the original values back (82 for speaker lines and 76 for headphones). All that can happen if you modify the wrong thing is: Your settings won't do anything or you'll have no sound, that's why a backup is ideal.
Features:
Louder Stereo Speaker sound system wide;
Louder Headphone sound;
Stereo Voice-Speaker call - NOT TESTED! Keep a backup and please let me know if it's working;
Customizable as you see fit! Just stick to the already explored options.
Conflict-free tweaks - no additional files added, no nothing, just some modified lines - you can trust it .
Installation:
By flashing the .zip on recovery or with FLASHFIRE [press the red "+" button > Flash ZIP or OTA > leave the options as they are and Click on the "done arrow thingy".
Manually copying the file to /etc - DO NOT forget to set the right permissions (RW R R). Please take a look over the Permissions.png screenshot in case you don't know how to set them - you long click on the file, then go to properties and you'll see the permissions button.
Do it yourself - there's a guide down bellow.
In the download section you'll find:
>>Flashable! already modified "Xperia X P Getting Loud.zip" with: SPEAKER values - 84 for both RX7/RX8 and HEADPHONE values - 84 for RX1/RX2.
>>Flashable! Stock Values - it's the stock file unmodified.
>>NON-Flashable! zips - there you have 1 zip for the modified file and the stock one so you can place it manually via ES file explorer or the explorer of your choosing.
**And some screenshots that are pretty self explanatory showing you what modifications need to be made if you want to do it yourself.
DIY Guide (using ES File Explorer):
You're probably acquainted with ES File Explorer so it should be pretty simple. The modifications I made were done with ES (it has an built-in editor).
1. Make sure the Root Explorer toggle is On - it's located in the Tools tab as you swipe the left side of the screen;
2. Go to the root of the files where you'll see folders such as "data; dev; firmware; storage; system; etc" go to "etc" folder and scroll down till you see the mixer_paths files;
3. Open "mixer_paths_tasha" and at the prompt, select ES Note Editor - it's a huge file so tap right above the navigation bar! A bar with percentage should show up - it will help you navigate through the file;
4.1 Speakers - Get to 45% of the file where you should see the path for "speaker", ctrl name RX7 and RX8 with their stock values - modify the values as you please but please don't go over 85 - sound will be too distorted;
4.2 Headphones - Go to 57% of the file - you'll see "headphones" path - ctrl name RX1 and RX2 - modify the values but anything more than 84 might be too much.
5. Save and reboot. If you choose to modify the files on a PC make sure to set the permissions when you put the file back. Otherwise bootloops might occur.
*Stereo Voice-Speaker call is untested but in theory it should work, as it does on my Xperia X. I added the second channel to the routing - screenshot bellow.
**Stereo Ringtone-Speaker - WIP. I'm currently stuck so feel free to jump in and notify me via PM.
***Internal players such as Music, Video, ringing and notification will try to compensate the sound so it might not be as loud as expected. But try a youtube video and you'll notice the difference.
***Do not attempt to modify something else unless you know what you're doing - on that note, make a backup first. In my first attempts I lost sound device wide with FC for sound effects apk.
***Do not go over the values I imputed (84 for speaker and 85 for headphone) - apart from the distortions that will occur because of the louder volume the internal DAC might not be able to reproduce the sound at such intensity - in my tests one of the speakers was shutting down. Again, no harm can come to your device but don't push it.
***I saw a lot of sections for hi-res headphones, Noise cancelling, etc - I did not explore those options because I don't have the means to test it. Any input and contributions from you guys are most welcome.
These files control the volume output for digital / analog which means it's a non-intrusive way to change volumes with no harm for the device. If volume limit exceeds the capacity of the speakers it will sound bad but there is no chance for physical damage.
I'm coming from a highly modded Xperia Z (that phone saw some torture) which made use of the earpiece speaker for stereo, and even if the speakers aren't designed for that output they are louder than the X which packs pretty decent speakers. This is the mod that gave me the idea: http://forum.xda-developers.com/xperia-z/themes-apps/mod-stereomod-xz-v1-1-t2835995

Yes that's why it's a guide-ish. Files are different still... Traditionally with Sony, you should aim for the largest file. In your case the right file should be "...tasha" file. If you want you can send it to me or try it yourself. Keep a backup. I had no bootloops (so there's nothing to fear) by modifying what I shouldn't (and i had a dozen of tries). All that can happen if you modify the wrong thing is: Your settings won't do anything or you'll have no sound, that's why a backup is ideal. PM me. I'm curious about the file and results.

It's simpler than it was on my X. I'll be back with an update. But I need my coffee first ))

Tested. It work. Whatsapp's Ringtone is obviously but some notification sound get distorted.
So I don't know the setting(84) is correct or not.

That's device specific. On my X 84 is just the right amount. I'll make another zip with 83 values. That's only one step over stock.
At least headphones are loud and distortion free. I noticed some good amplification on those. On my old Xperia Z I could never have such a powerful sound without signal cutting off on one of the channels.
Correction. The file had 85 for speakers. I'll put new zips with 84 soon.

Looks like it's mixer_paths_wcd9335.xml at 148.6KB. Both RX7 and RX8 are at 82 stock (under path name="wsa-speaker"). How much past the original values are you pushing these things, 2-3? Do these values boost the in-call speakerphone volume as well?
Unrelated, does anyone know if this XML has anything that could be modified to get get both speakers working when using the in-call speakerphone?

I am pretty sure both X and X compact use the same HW - it seems to be the same file and wsa thingy - check my thread for X - https://forum.xda-developers.com/xperia-x/themes/xperia-x-mixerpaths-volume-tweaks-tank-t3525691
it is possible to modify the call speaker - and there are more things to add like stereo for that one. But going over default for one speaker can get voice distorted. And if stereo is applied there, than microphone quality will drop a lot. There's a reason why the call speaker is mono - so that the mic on the other side can catch most of the sounds. At some point maybe I'll look for a hook for stereo.

Awesome! Bumped the speaker and headphone values up to 86 and 85 and all I can say is wow! Made a huge difference!
Do you know which lines specifically control the in-call speaker volume? Makes sense about the mono audio/mic pick-up, however it'd be great to at least increase the volume.

Adding stereo speaker to phone call is a bit tricky as far as I remember, especially without a recovery. Hopefully I'll have some spare time to look over it or at least identify call routing.

Would it be easier to just increase the in-call volume and leave it mono? I'm guessing that there is a similar RX line that can be bumped up a few values to increase the volume.
Under <path name="voice-speaker"> there is a line <ctl name="RX8 Digital Volume" value="82" />. I'm guessing that may be it?

yup, that should be it. I'm advocating for the stereo because stock values already distort a lot on speaker call

Question about increasing volume.

Hi, Im not sure if this is right place to post this. I've never rooted phone before, and i want to root my Xperia Z5 Dual, only because i heard you can increase volume. This phone has low headphone volume IMO. i can listen without problem in quiet places but sometime when im outside i cant hear song even in full volume. even my Iphone 4 had louder volume. So what i wanted to ask is if i increase volume when i root, will it decrease sound quality? there are some apps that dont require root to increase volume but then phone sounds terrible so is it worth it to root my phone for this reason? I'm aware i might brick the phone too.

AFAIK you can increase the headphone volume by editing "root dir/etc/mixer_paths.xml" and finding <path name="headphones"> and editing values from there.
I'm not exactly sure what values to change as I had only done this a long, long while ago with my old Z3. A quick google search will get you going though.
Rooting shouldn't decrease quality but unlocking the bootloader MAY (and I mean may because I am not sure what unlocking the bootloader disables on this specific device) disable some sony sound 'enhancement' software on the stock ROM.

Another option (and the way I do it) is to root using magisk and install magisk manager. Then through the manager you can download and install modules. You'll want to install the "ViPER4Android FX" module by ViPER520, ZhuHang, Ahrion, and Zackptg5. Within the viper4android app you can set various sound enhancements. Just looking through real quick I can see output gain and playback agc settings.
If viper4android is not processing/enabled you can try going into your phone sound > accessory settings and turn on automatic optimization and/or install the magisk module "Audio Compatibility Patch"
