That helped to get the drivers installed! I can't get it to work on lp no matter what I try. Might need a permissive kernel for it to work right.

Download SELinuxModeChanger from. The play store tap permissive, reboot I stall driver again reboot and you should be good to go.

Once copied change the permissions to match the other files in the /system/etc folder

Install Viper and it should work this time, apparently the audio.effects.conf file is expected to be in the /system/etc location and is not there by default for some reason....

For advanced users I suppose you could just create a symlink to the other location also but I didn't try this myself.

let me know if this works for everybody else, so far it has worked on both of my Tab's

Make sure to cruise by the Viper thread and thank metaljim also as he gave me the initial help which headed me in the direction of adding the file to system etc.

Installed it perfectly thanks! Problem now is that it has NO EFFECT at all on the sound. Disabling and enabling it has no effect whatsoever on the audio output

EDIT: IDK if the SELinuxModeChanger being permissive helped at all, but I did it anyway. What I found out later was that the only way of activating Viper4Android's effect properly is if you (install Poweramp) and go into Audio>Advanced Tweaks> Tick "Direct Volume Control" and untick "Direct Volume Control" again after. You need to leave it at off. Somehow after doing this Viper works for all apps. However, this is only temporary as the effect goes away after a reboot. Forcing you to do this again and again. !!!!!

Weird for sure, I do not have that problem on any of my devices. Best bet is to try the original Viper thread. Somebody there may be able to help you. You can also try freezing or removing sound fx and disabling nuplayer in developing options. That is if you haven't already.

thank you for that information but I don't need to copy or symlink audio_effects.conf. On my SM-T805 with Lollipop 5.0.2 (T805XXU1BOCC) this file can be found in /system/etc while /system/vendor/etc only contains folders.

Talking Viper4android 2.3.4.0 on Samsung Galaxy Tab S 8.4 <> SM-T700 <> klimtwifi
FIRSTLY: This works on my Samsung Galaxy Tab S 8.4 <> SM-T700 <> klimtwifi with
aicp_klimtwifi_lp-10.0-NIGHTLY-20150813

SECONDLY: This is not my work. I found it somewhere a few weeks ago. I tried to find it again so I could simply point you to it. That would have been much easier.

After dozens of hours trying to get Viper4android to actually have an effect on the audio I found a solution. I used xda references to help me install Viper4android 2.3.4.0 (look elsewhere for help on that, if needed). However, I had to do these additional things for the app to have to *actually have any effect*:
(files attached below)

- Go to
Root folder "/system/etc" & replace the*audio_effects.conf*with the one provided
Root folder "/vendor/etc" &*replace the*audio_effects.conf*with the one provided.
Root folder "/system/lib/soundfx" & add all the libs provided (replace any if needed).

Take care that you don't mess with*audio_policy.conf.

Now just setup your Viper and reboot.
