Not here it doesn't. FX driver doesnt initialise properly, XHIFI works but has little effect because the FX doesn't work.

This seems to be a lot better than acid for me (maybe i havent configured both properly)

Both mort player and vlc are louder for music and films but netflix seems the same :-s Is it likely netflix is actually louder and it's been a long day?

cheers

Well I got Viper to work on CM after a factory reset.

I couldn't find a place to extract the samples to as I can't find the directory mentioned in the OP... so it's just sitting on the SD card for now until I figure out what to do with it.


I am a novice when it comes to audio settings, so if anyone could help me out on a recommended setup for the speakers (not headphones) that would be much appreciated! :eek:

Never thought to create the folder mentioned?

I actually let Viper do that for me. If you press the convolver option, it will create the directory and then ask to place the IR samples in it.

I was thinking of creating it myself, but wasn't sure if there was supposed to be other stuff in the folder (I didn't have a Viper folder anywhere on the kindle to begin with).

FX works: Stock Rom 7.3.1

I have the rooted stock rom 7.3.1. and just installed the FX (following the steps of first post) and it´s working!
Thx!

As said in the faq I followed afterwards these instructions, too:
- Why there is background noise when using v4a effects?
Rename /system/lib/soundfx/libbundlewrapper.so to libbundlewrapper.so.bak, reboot device.

Im on Paranoid Rom for Kindle Fire HD 7 and this works nicely. I was annoyed at how low my headset volume output was compared to my SGS3 phone. This helped greatly and it sounds great, thanks!!!

Quick note, and I've seen it mentioned, you CAN create the directory yourself (in the root of the SDCARD\viper4android\kernel ) Place the IR files there and it found them in the apps.

New update out that works with android 4.3. Testing now and seems to work fine with cm10.2 !!

Sent from my Amazon Kindle Fire HD using XDA Premium 4 mobile app

I've got it working also on CM10.2 . Now I am trying to figure out how to uninstall/delete/disable DSP Manager (sys file) with no luck. I've tried using Root Broswer and Root Uninstaller Pro with no luck. Any thoughts on how to remove DSP Manager?

EDIT: ok, did some more searching and I was finally able to remove DSP Manager as "su" with Terminal Emulator using the following command to mount the system folder:

mount -o remount,rw /system

then I just deleted the file in its directory

rm DSPManager.apk

Not sure of which file/link you are referencing; however, you might try the Google Play Store. This is where I downloaded my viper4android fx for 4.3, which had a lot of Chinese writing.
