[Android Q&A, Help & Troubleshooting] therussian87:
so I got it installed on my oneplus 3 by using the divine beats zip.

the thing is when I connected my phone with my Bluetooth speaker it said "cannot play media" or something along those lines.

I tried another player but same issue and it some how removed the drivers I think. when I check driver status everything is proper before I had connected to Bluetooth. I even rebooted to see if maybe the drivers didn't stick but they where fine with headphones and phone speaker. as soon as I connect Bluetooth speaker it looks like drivers aren't installed anymore when checking driver status. I connect headphones again and same thing it shows driver isn't installed or something.

So I uninstall drivers, reboot then install drivers, reboot and all is good. it's only when I connect Bluetooth that Viper stops working? anyone else having this issue? any fix?

Hi, LG G3, D851, stock v6, rooted, xposed. Viper 2.4.0.1 is working, processing, but I can't seem to get it to see irs files. Keeps saying storage/emulated/legacy/...kernel is empty. Got files in there too when I look on root explorer. I know that directory had some funny characteristics tho, actually have to put the files on the regular sd, so wondering if there is a trick...? Followed suggestions on page 47, permissions on the legacy folders are 771, while the source folders on the sd are 770. Installed as system app, no help.

If you enable speakers in poweramp it should do just that. It may need further configuration as well.

However do note if your using a console it will kill your battery faster for each notification that plays.

Also note that people have Complained of a delay when talking on the phone with viper enabled. This effected certain device/rom combos.

There has been issues with ES Explorer. As well as some other root explorers.

Help with Viper4android

I have a Sprint HTC one max rooted and s-off, stock rom, flykernal 2.3.2. i have v4a working on my phone and have found out that i can ONLY use it with google music player. I know on the htc one beats edition, you have an option to choose v4a in "music effects" under sound settings. the one max has no such ability in sound settings. is there a way to make v4a the native audio effect? i absolutley love v4a and really wanna make it useable on all my players on my phone, xbox music, pandora, etc.. any help would be much appreciated!

Update: did a nandroid backup and used titanium backup to uninstall a service called music enhancer. the phone force rebooted itself, but so far v4a is working on every app! That was about 8 hours ago with no reported problems... Will update here if I experience any problems... Hope this helps someone that was having the same problems as me..

When you got an DAC, it works

On my G3 5.0 its only works with build in player or google music.

But when i plug in my Fiio E18 DAC/AMP, then viper its works with power amp (must only lock headphone mode)

and it works, too, whether I unplugg it again. Viper stops then only when i force quite it via tastmanager or restart phone.

Eventually its possivle to program an emulated DAC or something, Thin not everybody whant spend around 180€.

(but the fiio its worth, g3 and m7 have good sound, but not so good that u can use custom IEMs without an external DAC)

But with every 5.0 rom, with or without viper, i got noise (zkrzkrzkrez) when i touch the screen or star app for 3-4 seconds...

Sorry for babelfish translation, hope my can understand me^^

Sorry if this has been answered before, I've tried searching for it and even testing myself, but to no avail =(

Alright, so this app was recommended to me by some people and I decided to try it. Like every other equalizer, mod or app that I've tried, it does not work -for me-.

I have tried volume+, this app and some equalizers. Different players even when running the viper4android. I have the drivers installed and busybox. I went deep enough to even see if the LPA was disabled and it was. I have followed all instructions, but nothing seems to work for me. I have a galaxy s4 GT-I9515 and so far I can barely find something that was worth voiding my warranty....

It was only until recently I learned that there are no custom ROMs available for my device, because of touchwizz and 9515 having a different kernel than 9505. And now this doesn't work too, and all I want is to be able to listen to my God damn music loudly from my headphones like I could on my iPhone.

Please someone help. I am running stock 4.4.2 android, if that was not clear.
[Android Q&A, Help & Troubleshooting] dioxide95:
1. If you have actually tried everything and it does not work, you should try for the last time. Do a fresh install of viper and check compatibility mode. Try it with Poweramp.

2. If you still fail, download and pay for Poweramp. It is the best music player available on the store. Viper makes it better though, with surround sound and all.

3. Contact the devs directly. Ask them if Viper is compatible with your phone.

4. Buy a Nexus, the next time ;)

Rooted yesterday. Booted with viper. Treated to ears. :eek:

---------- Post added at 01:12 PM ---------- Previous post was at 01:01 PM ----------

Its normal. Keep internet on. Click install in busybox. It will say checking system.

In around 5 minutes install viper drivers from viper apk and don't worry about busy box installing status.

Check status of viper driver status from menu after restart.

It happened to me yesterday. I fixed it. One more method is to apply .prop and lib zip files from recovery. It won't be detected by apk but after couple of restarts it will apply driver.

Check last post of original dev thread. There are 3 simple steps. Hope this helps. Finally a word compatibility mode does not work for me.

[Android Q&A, Help & Troubleshooting] vikraminside:
Go to Android settings - Sound - Audio effects - viper4Android - Always button (Moto g equivalent).

You can uninstall other audio effects app if installed. It will suppress audio in combination. Switch off stock audio effects app if on.

Once viper is enabled as "always" stock player equalizer can be turned off too feel the effects. Multiple equalizer along with viper suppresses the volume. Play around with viper to get best effect.

I recommend Viper Bass maximum hertz setting in moderate UI (viper settings menu)

Viper can work across all apps that uses sound including stock and other music players.

I'm very into my audio, but my phone is used for music primarily in my car, where through amp settings and speaker choices, the sound is already perfectly tuned to my liking. I would never want to apply any equalization, surround effects, reverb, nothing. Everything is already exactly how I want it. What I want is a very pure, loud source signal with no distortion at all. If I'm not going to use any equalization, surround effects, etc etc, will this make my source cleaner, louder, or lower in distortion than the stock driver for a galaxy s5? I'm a computer tech and always rooted, but modifying my build.prop will prevent my phone from getting any further ota updates even if nothing else this app does would, so I'd need to see improvements of the specific type i mentioned to be willing to try it, since I like to keep my phone fully up to date.
