Okay my fellow Nexus 5 brothers and sisters, I have found a solution to V4A not working for some people. I give all the credit to a fellow user, nicknamed "JR", for reporting this fix and I hope everyone will find this helpful.

So, firstly, what's wrong? Some users have reported that V4A is not working, and by 'not working' it means that even when V4A is 'Enabled' within the app the app is NOT 'Processing'.

So to be clear, when I say V4A is not working the "Driver Status" within the App will report something like this.

Driver Version: XXXX
NEON Enabled: Yes
Enabled: Yes
Status: Normal
Processing: NO <-- Culprit
Type: XXXX
Sampling Rate: XXXX
Channels: XXXXX

So what to do to fix this? Firstly, let's start off with a CLEAN SLATE. Uninstall BOTH your Music Player and V4A (I used doubleTwist).
When both are uninstalled proceed to install V4A the normal way, HOWEVER, with a little variation.

Research from "JR" has stated that when USERS install V4A under System>App, the system still ends up killing the process hence why it no longer 'Processes' the audio stream. The reason for this is that under 4.4+ KK, System files are split into 2 different categories (am not 100% sure why). There is the SYSTEM>APP and there is SYSTEM>PRIV-APP. V4A should be installed in the latter (Priv-App) as this is the system folder that gets ignored from being killed by the Android System.

Make sure when you CUT and PASTE V4A into SYSTEM>PRIV-APP you change the PERMISSIONS to -rw-r-- r--
Once that is done then REBOOT.

After finishing reboot go into your SETTINGS. Under SOUND>Music Effects change it from MusicFX to V4A.
Once that's done then go to V4A App and install your preferred sound driver (Super, High, Batt Saver). REBOOT

After rebooting proceed to install your preferred 3rd party Music Player. Now this step is a little tricky as for me I had to delete a folder in my "SDCARD" called doubleTwist. I'm not sure of the process for any other Music Player. The trick is to make sure the APP is running as FRESH as possible, just like if you were to run it after a full wipe.

Once your music player is installed, try to play a song and let it play.

Go into V4A App whilst the song is playing and TICK ENABLE on the applicable heading (Headset, Speaker etc.)
Once you've enabled it then go to your Driver Status and CHECK if it says Processing: YES.

If that's the case then you're good! You're all set up. Having V4A under System>Priv-App and not in System>App will prevent it from being killed by the android system.

Hopefully this is helpful for my Nexus 5 comrades. I was about to give up on this app when that person told me how to fix it. Just spreading the love. :fingers-crossed:

With this VHS+, V4A made its way to achieve great surround technologies for Android.

★ Auditory System Protection (Cure Tech+) ★
With normal audio system, listening for more than three hours will feel fatigue, dizzy, tinnitus, irritated and other symptoms.
This is a normal reaction, heavy bass and high volume could cause permanent damage to the human auditory system, but other phenomena can restore through resting.
Viper as a listening experience professional will not ignore this problem. Therefore put a lot of effort to study how to make a "Healing" sound technology, just a small success. But thinking on how to let users experience it.

★ Convolver ★
When an Impulse Response Sample(IRS) is loaded, V4A will process the sound to show the same characteristics of the loaded sample. Through Convolution, samples with effects such as equalizer, surround, reverberation, tube etc can be loaded.
Download and extract IRS files to <storage>/ViPER4Android/Kernel/<paste files here>

★ FX Compatible Mode (Only in 4.x) ★
Compatible Mode supports large variety of music players and the players' own EQ/sound effects (system-provided/third party)
Therefore, you don't have to select V4A in Sound Settings > Music Effects, choose anything other than V4A. Just run V4A app and the effects will be working with anything else.
1. In option, switch to Compatible Mode. Reboot, done.
2. In Sound Settings > Music Effects, choose other than V4A.
3. Run V4A app and configure the settings then the effects will work together with the one you chose in Sound Settings.
