Does it are a difference in sound if I use it with the speakers? Or only in headphones?

Yes but from what I noticed it doesn't affect the stock music player.

Same...lol

Oh really? I didn't know I don't have music on my phone I use spotify

 

[lmario346]

I dont think the stock music player won't work with all equalizers

 

[bennyben]

Works great with Pandora. Maybe if you use another music player besides the stock it might change

 

[lmario346]

It works with every music app except stock

[lmario346]

[lmario346]

I founded out it doesn't work with all music players except internet radio like pandora iheartradio spotify

I know how to play music on your music player
1) Download bulid prop editor from the play store
2) open it and find lpa.decode and set it to false
3)find lpa.use-stagefright and also set it to false
4) reboot
5) your music should be working with ViPER4Android on any music player

to add to what lmario is saying (I looked this up because simple fixes without knowing wtf I did is pointless if I don't know how it was an issue, could come back up, be worse, etc) what you are doing with this fix is turning off your "low power audio".
This question in google groups has the OP explain it pretty well

Now this question wasn't answered when it was posted, however putting that info together with v4a's compatibility issue and its plain to see this power saving feature built into our phones is the culprit (good for battery, bad for sound quality)

lmario's solution works to disable it, if you don't want extra junk on your phone though, with a root file explorer just go edit your /system/build.prop file (probably need to edit permissions to do so). Either way solves the issue

Edit: almost forgot, stagefright is specifically for streaming, the decode line is for music files stored, doesn't change the fact both should be set to false, just more info

 

[lmario346]

I didnt know stagefrieght is for streaming im only 15 years old im starting to know stuff about Android

 

[s810car]

it actually is for both, i looked into it some more and was mistaken partially, here's some detail on the API
