[Q] MusicFx has stopped working.

Hey i just got my Nexus 7 a couple days ago and successfully rooted it at 4.2.1 stock android.
Ive installed only a couple of apps and everything seems to be working. Then one day i decided
to try Beats Audio Installer Pro for Root v1.2. I installed it successfully. After loading my equalizer in
the stock google play, it loaded many equaliser bars than the stock 5 and then i tried changing them to test it. Nothing changed
even when i toggled it on or off. Then i decided to uninstall it. It reboots and loads normally.
Now when i clicked on my equalizer settign in the stock google play, it says: 'MusicFX has stopped'.
I tried factory reset and got nothing. At stock rooted, its still comes up with 'MusicFX has stopped'.
Even tried installing other equalisers on the market and they all stop working since im sure
the stock MusicFX process is needed for them to work. I have nothing else to try.
Help would be nice or i might return the device back to stock unrooted and check for warranty or something.
Thanks.
Obviously reinstalling stock will fix it. Because I am also having same problem but i don't wanna install stock again just for equilizer because my previous settings for musicfx seems to be working till now. If you get solution without installing stock again then plz do tell me. I am also waiting here eagerly.
Still no luck. MusicFX is still not working on my phone but but but I installed ROCKET MUSIC PLAYER, It comes with own equilizer and it's working fine whereas equilizers of other music apps are not working.

Using root browser you can copy audio configuration in other rooted nexus7 and paste in your your system/etc and also copy soundFX and paste in your system/ lib soundfx folder and change the permission to rw.r.r and reboot your device..but remember u need to delete all the files inserted by beats..you find it in your system/lib,system/etc,and system/bin.
sorry about the wait
I had totally forgot about this thread since i left my tablet for a long time.
How i fixed it was just returning it to the original rom. It was the new rom indeed and beats not being compatible with my nexus 7. It seems Beats trys to take over musix fx and stops it from working. I just tried other roms instead without beats and everything was fine. Seems beats doesn't work some some devices.
Anyway atm, my nexus 7 is dead and posted prior to this one.

IT works with music stock player... but NOT with poweramp!! what to do??
Solved

Anyone got viper4android to work?

I've tried this method - http://forum.xda-developers.com/galaxy-s6-edge/themes-apps/viper4android-s6-edge-root-t3072183
and it didn't work
Yes! One of the main reasons I'm rooted is viper4android. I've flashed zip from this thread http://forum.xda-developers.com/galaxy-s6/themes-apps/viper4android-neon-enable-including-t3139893
Hey. I just installed Viper4Android and immediately checked with PowerAmp then nothing changed about the sound. So i activated the MusicFx option from PowerAmp's settings and now its working.

Viper4Android System Wide

Hello,
I recently clean flashed stock 5.1.1 and installed Viper4Android but I cannot seem to get it to work system wide. It works fine through play music but it won't process for youtube, etc. I am using the latest Viper4Android version, latest busybox and SELinux is permissive. I moved the apk to /system/priv-app, rebooted, installed drivers, rebooted, then started setting it up. I don't know if this is a problem with the way I set it up or if it is simply because I am using a stock ROM. I have another device with Cyanogenmod and Viper4Android processes for everything. Any advice would be appreciated. Thanks.
I also installed Viper 2.3.3 over 5.1.1 but flashed it from recovery as it was suggested in one of the XDA posts. Also flashed build.prop and lib fixes that came with it. For some reason that flash cleared davlik cache, may that's the requirement for Viper. I think Viper is OK with YouTube but it's hard to say as sound is always different. Sometimes its low. Highly promoted Vevo videos sound loud.

I managed to get it working system wide shortly after posting. I first fully removed my existing V4A installation, by uninstalling the driver, deleting data and uninstalling the app through link2sd. I rebooted and then downloaded the viperlolli zip from the nexus 5 forums, extracted it, replaced the apk with the latest version, renamed the apk folder, re-zipped and flashed. I then installed the driver, rebooted, set it up, and it is processing system wide (Youtube, Spotify, Chrome Beta, Play Music, etc). I don't know what changes the author did in the zip, but it worked wonders.

modules flashed on Magisk not showing up after immediate reboot.

Hi i'm new to this site and a newbie to ROMs and stuff. I flashed Viper4android fx legacy from Magisk and after rebooting my Asus zenfone max pro m2(LineageOS 16) the app still doesn't show up.
I've downloaded a couple of modules from Magisk and they all work just fine but when it comes to audio mods it's not showing up after flash(downloaded James DSP, same result as Viper).
I downloaded Ainur Narsil and Audio Modification Library too. Do they cause any problems(it said legacy device detected)? Either way i don't feel any difference.
Tl;Dr: Magisk Flashed audio mod not showing up after reboot.
P.S: are there any better audio mods?
This video helps i think give it a try
