Viper4Android returns sound great but complex to set up "on the go" (ie quickly change a parameter)

The app and its MaxxAudio sound drivers available from CM12S on features excellent high and low, to the detriment Surround effect that can often drastically worsens the quality of the song you are listening. In addition the low that returns are not dynamic, and what feels distinctly in some parts.

So let's seehow to use simultaneously the two drivers:

WARNING:

MaxxAudio (Updated) : https://www.androidfilehost.com/?fid=24499762636003406

Poweramp or Blackplayer and MX Player: only player which at the time the process has been tested, but I suppose that many others are compatible.

Disclaimer: I am not responsible for any Soft/Hard Brick. Try at your own risk.

Steps:

1. Place downloaded ZIP files on your Internal or External SD Card.

2. MAKE A BACKUP, VERY IMPORTANT! Things can happen.

3. Use TWRP Recovery to Flash the Zip File.

4. Reboot to recovery

5. Flash ViPER4MM.zip

6. Flash maxxaudio.zip

7. Reboot

8. Open maxxaudio app and turn on it

9. Open viper app and install the driver

10. Reboot

11. After reboot open maxxaudio app and disable it for phone and headphone both

12. Reboot again

13. Enjoy the power of music :);):D

Recommended Music player: PowerAMP

PowerAMP will work on Normal and Compatible Mode.

For Normal Mode you must Disable BOTH Direct Volume Control & BT Direct Volume Control even if you're on wired headphones, under "Settings>Audio>Advanced Tweaks" to Disable.

For Compatible Mode you are free to use DVC but you must Enable MusicFX under "Settings>Audio>Advanced Tweaks", then under Tone/VOL you can trigger the MusixFX button and V4A will work.

if you are on MM Based ROM and you have personal profiles to load,then

Goto: data\media\legacy\ViPER4android\Profile folder

Add your profiles

be sure to change the permissions of these files to rw-r-r, otherwise V4A can't read them and won't load them.

Enjoy V4A with MaxxAudio ... :);):D
