ViPER4Android driver install failed

[ifly4vamerica]

Well I installed the thunder rom and viper works on everything. Oh well

Weird I am on stock, just rooted and debloated and everything works a-ok. Glad you got it going!

 

[gggg]

OK all I have a fix for installing Viper on the Tab S.
Use any file explorer and navigate to /system/vendor/etc
Copy the audio.effects.conf in that location
Navigate to /system/etc and paste the file you copied there
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....

THX for your hints ... is this necessary as well on tab s ?

extract from system, and backup audio.effects.conf in both system/etc and system/vendor/etc
Insert under libraries section in both files

  v4a_fx {
   path /system/lib/soundfx/libv4a_fx_ics.so
  }
... and under the effects section again both files
  v4a_standard_fx  {
    library v4a_fx
    uuid 41d3c987-e6cf-11e3-a88a-11aba5d5c51b
   }

push back to thier places, set permissions, reboot.

Nope I didn't have to do that. Just follow my post and you should be good to go.

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.

Thank you very much for the solution. Only one thing: there is a typo. The filename isn't "audio.effects.conf" but "audio_effects.conf".

Here is the version I try with a Symlink and via ADB, which runs fine also:

- connect Tab S via usb-cable and open command shell with access to adb.exe

adb root
adb shell
mount -ro remount,rw /system
ln -s /system/vendor/etc/audio_effects.conf /system/etc/audio_effects.conf
exit

After a reboot the installation of Viper works.

help viper4android wont paste in the location.

audio_effects.conf (thats what it looks like)... it doesnt have the period between audio and effects.. :-/ and i cant paste it in the location.

Yeah the period was a typo. What file manager are you using? Are you enabling write permissions to the new folder? You can also create a symlink as described in the post above yours.

Viper driver won't install?????

In SuperSU

Settings

Enable Superuser (disable then enable it).

This worked......after several hours of paranoia.
Refused to create my rom* without Viper!

I pushed the file in the right place, installed driver succesfully but after that it does not work only in compatible mode and with spotify.. any help?

I have a problem with installing V4A on stock ANFB firmware.
After flashing zip in TWRP, device is restarting and during system startup i have "Android is upgrading..." message like after normal cache erase.
After "Optimising app xxx of xxx" I've got "Starting apps" message and system hangs on here.
When I do a reset by buttons my Tab hangs on Samsung logo, and I must restore system partition from my NANDroid backup.

How to properly install Viper4Android on Tab-S SM-T800?

EDIT:
OK, it's working. I installed V4A from Play Store and followed instructions in this thread.

EASY Viper4Android FX and XHIFI DRIVER Installation FIX

I wanted to post this to help others who may be struggling with driver installation as I was.

The FX driver installed with no problem, but no matter what I did, the XHIFI drivers would not install.

After extracting the apk of the final XHIFI version available which is Version: XHiFi version 2.1.0.2-1
Codename: X-Factor, I realized that;

1. the /system/etc/audio_effects.conf file did not include the references to the XHIFI drivers
2. the suggested file fixes I found in forums did not work, because they did not reference the latest XHIFI driver names used in the final apk

This is THE SOLUTION for both FX and XHIFI driver installation in case of the above scenario:

1. Unpack the apk and extract the drivers.
2. Find the one that is applicable to your device and add the reference into the library section.
3. Insert the driver file into the /system/lib/soundfx/ folder so that it can be found

This is my file:

libraries {
v4a_xhifi {
path /system/lib/soundfx/libv4a_xhifi_ics.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_ics.so
}
v4a_xhifi {
path /system/lib/soundfx/libv4a_xhifi_ics_NEON.so.jb
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_gb.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_ics_NEON.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_ics_NEON_HQ.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_jb_NEON.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_jb_NEON_HQ.so
}
v4a_fx {
path /system/lib/soundfx/libv4a_fx_jb_NEON_SQ.so
}

I wasn't absolutely certain about which NEON driver was for my Samsung Galaxy S4 Verizon SCH-1545, using SafeStrap and Stock Rooted ROM, so I included all of them, with no problems as a result.

I rebooted and all was running in tandem.

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.

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.

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.

FOR THOSE WHO CAN FLASH ZIP FILES

On my SM-T700 this works perfectly every time no problems etc., etc........

Flash the ViPER4Android-supolicy.zip found at the link below to take care of the "permissive" mode that is required for Viper4Android to be installed.

Flash the LolliViPER_TAB_S.zip.

Reboot, Rock Out, and Profit!!!!
