I've been using the Sony MEX-BT5000 with my Wizard for 6 weeks now. The Sony headunit supports the following BT profiles:

A2DP -- for streaming music

AVRCP -- for controlling media player

OPP -- for transferring phonebook entries

HFP -- hands-free profile for phone

When I get a phone call, the radio/CD mutes and displays the caller ID info; pressing a button on the Sony answers the phone. Speakerphone performance is very good -- the mic is hidden behind the faceplate, but it still picks up your voice. When the call is over, the radio or CD resumes.

I haven't done much with A2DP/AVRCP yet, but the A2DP is at least as good as that in the Moto HT820, based on some brief tests. Also, if you run nav software that gives directions, the directions should come over the car speakers -- haven't tried that yet.
[8125, K-JAM, P4300, MDA Vario General] makelly2:
A2DP/AVRCP require a particular ROM, correct?

Would all headunits that are bluetooth enabled support those BT profiles?

Thanks for the info. Will definitely look into that particular headunit.

Appreciate the help,

MK.
[8125, K-JAM, P4300, MDA Vario General] 3waygeek:
A2DP/AVRCP are built into most of the customized ROMs that used to be here -- I used the Tornado A2DP hack instead. AFAIK, only the Sony headunit supports A2DP/AVRCP. You might also want to look at the Sony MEX-BT2500, just announced today -- its price is somewhat lower than the 5000.
[8125, K-JAM, P4300, MDA Vario General] makelly2:
Nice. Thanks for the info. Both of those headunits have the functionality that I want. Perfect.

Found out that I do have A2DP/AVRCP, so I'm set. Now I have to either impluse on the BT5000 or wait for the BT2500.

Thanks for the help. I really do appreciate it.

Can anyone having both confirm the difference in quality and battery drain?

Have u tried V4A in the past? If not please try.

U will notice difference when u use V4A with Expert Ui mode setting. Battery drain, i dont worry.

I've tried it on Candy5 ROM as well as daleski's nightlies, but it doesn't seem to work. I look at the driver status and it says it isn't active. Also, every time I open the app, it asks me to install/update the drivers when I clearly did already.
[ONE Themes and Apps] bashrulz:
I believe it's because of the SELinux mode..

Set it to Permissive instead of Enforcing using this Application. and let me know if it work's or not :)

Damn, changing to permissive and still won't install drivers. Anything else that needs to be done (I disabled nuplayer already). Thanks.
[ONE Themes and Apps] Edu13:
You need to make sure all other FX audio mods are disabled. Next use Power Amp enable FX in music settings and make sure you disable tone and equalizer. Remember you also need busy box installed. As far as in Viper you are flashing and do not have any other version installed. Lastly some ROMS already have SE Linux set to permissive, and in Viper options try compatible mode.
[ONE Themes and Apps] srikanth_s:
I'm guessing its bcoz of previous flashed mods. If nothing works, try to switch to compatible mode in V4A setting.

[ONE Themes and Apps] vivekchamoli:
Just follow 5 simple steps.( no zips required to flash).

1. Change Enforce mode to permissive mode using SeLinuxmodechanger from playstore .

2.Disable experimental "nu player" from development section search "nu" you will get disable it.

3. Disable Audiofx app.

4. Now install viper4Android and install driver ( i user superior audio ) .

5. Reboot.( and experience the amazing sound).

[ONE Themes and Apps] remix96:

[ONE Themes and Apps] Irseq:
Because you don't need to do it on KitKat. You just install it.
[ONE Themes and Apps] remix96:
But when i open Viper i install the driver and then when i reboot it re-ask me to reinstall the driver :confused:
[ONE Themes and Apps] vivekchamoli:
Check busybox with supersu properly installed that the issue.
[ONE Themes and Apps] remix96:
I don't know how to do that, i've only supersu installed as far as i know. Can you please explain me how to do that?

EDIT: With root checker pro i verified the root and busybox and it is installed. I don't know what i should do, what viper says is uploaded.
[ONE Themes and Apps] vivekchamoli:
Viper is installed as per the screenshot , you need to disable audiofx to make it work and reboot.( kitkat only) . for lolipop you need to disable audiofx & nu player from development section -- search as "nu"..you will get it disable that experimental feature.(lolipop only. And also make selinux to permissive mode use app from playstore. And after that reboot the phone.
[ONE Themes and Apps] blackdale:

Which file to be flashed first? The second and the last or that is not important.
[ONE Themes and Apps] srikanth_s:
I see that ur using Nexus 7. Mod should work on Nexus 7 too.

I suggest you to do backup in recovery before flashing mod zips. If the mod fails, u can remove the mod changes by restore option in recovery.

Not sure whether order of flash matters. Here is the order which I followed.

Viper4A-_Build.Prop-Tweaks_-CWM.zip

Viper4A-_Soundfix-LibFiles_-CWM.zip

viper_v2.3.3.0.zip

Hey guys.

Just install viper4android successfully, but i dont know it works or not.

In normal mode, i can see driver status. But when i change to fx competatie ( not sure write correctly) i could not check driver status.

Also, i could not find " music effect " in setting to change it to " viper effect ". Just google and it is said that in lollipop, we could not see music effect in setting/ sound

Please, help

Thankn you

[ONE Themes and Apps] srikanth_s:
Not sure about cause. Check if it causing due to Speaker/Headphone settings in V4A.
[ONE Themes and Apps] srikanth_s:
Follow the below steps:

Make sure SE Linuxstatus is Permissive (in Setting->About phone) and NuPLayer is disabled in Developer Options.Then flash the Mod zips in recovery.Boot the phone.

Launch V4A app.It will prompt u to install driver. If not select Install driver from app menu. Install driver by following the steps. After the driver install , go for phone reboot.

Launch V4A app. See Driver Status from app menu. If it says Abnormal status, then Mod failed.
[ONE Themes and Apps] thang vu:
I followed step by step. Reboot the phone and it dont require for install driver more.

The problem is when viper4android is normal mode, i can check the driver, it says like this

Driver version: 2.3.30

Neon enable: yes

Enable: no

Status: normal

Audio format: supported

Processing: no

Sample rate: 44100

But when i change to compatible mode ( in fx compatible) i can not check the driver status, it was hidden ( i could see it but could not to tap it) but i could see the option " uninstall driver "

So did i success in installing or not?

Also, what could i do next? To get the best sound on my nexus. I often use it to listening English everyday so, it will be great meaning if u can help me to finish this.

Thank you very much!
[ONE Themes and Apps] srikanth_s:
Looks like Mod installed correctly. Uncheck FX Compatible. Check the "Enable" first checkbox under Speaker and headphone tabs.

For best audio effects Switch to Expert Mode in UI Settings from app menu. Try out the different setting like Convolver,differential sound, bass, clarity etc.

For Convolver : Download some IRS file .(eg: http://xdaforums.com/showthread.php?t=2439254).Copy to "VPER44Android\Kernel" folder in sdcard. Now enable Convolver checkbox and try out different IRS audio effects.
[ONE Themes and Apps] Nexus5-32GB:
I love Viper4Andoird and works like a charm on KitKat roms, however on Lollipop the problem I have is buzzing, stopping playback, hickups while playing songs (worse on FLAC songs). All the effects works as it should but the only thing is these errors during playback. I have tried many solutions (including the one from first post), but nothing worked so far :(

Thats why I use KitKat as daily driver, could not make it to work without sound issues on Lollipop...
[ONE Themes and Apps] rayandreas:
I did what the op said and it is working for me on LP euphoria 01/29/15 rom. I flashed all three in order, rebooted, installed se-linux changer from play store and put to permissive. Checked in settings and I was good. Rebooted then opened viper and flashed driver, then rebooted. Opened up power amp and did what I needed in it and it works! Thanks a lot. Like someone else had stated, I wouldn't stay on lollipop for a while because of this, but now it is working so far like a charm Thanks for sharing the great insight!
[ONE Themes and Apps] galupo:
Had the same issue still not working.

Selinux set to permissive.
[ONE Themes and Apps] bashrulz:
Installed the driver?
[ONE Themes and Apps] Neon Black:
After enabling the driver all sounds comes from the earpiece rather than the phone speakers. Did a bit of digging and this seems to be down to \system\etc\mixer_paths.xml. When comparing the file versions from the download in this thread to the One Plus default and CM12 version they are significantly different (100's of lines). So I suppose it's not as easy as replacing one with another? Any clue what interfaces I'm looking at changing to fix this? :eek:
[ONE Themes and Apps] galupo:
Won't install
[ONE Themes and Apps] tinted:
Worked for me

I had the same issue, divers were installing repeatedly

But setting it to permissive made it to work

So what it this setting that I had changed?

And should I change it back when viper supports lollipop officially?

V4A got updated to 2.3.4.0 anyone tried it yet?
[ONE Themes and Apps] mssam:
Yep! Updated it last night. IMO, it definitely produces a better sound than 2.3.30 with earphones on the 05Q build. I'll try it thru the Bluetooth in my car in a couple of hours. I hope it sounds a lot better there than before. Of course, I did the usual and stopped/disabled audiofx and deleted the other three apks, but something still just didn't sound right to me with 2.3.3.0 on the opo or in my vehicle. Didn't see a need to edit the build.prop and I love how it's already set in the sound settings. I've been testing Play with viper and when I go to change the eq, it opens viper right up! Haven't tried poweramp yet, but... definitely, give it a try, if you haven't yet...

Help needed.

Hi guys. I am on CM12 nightly and flashed the files, absolutely incredible sound on my headphones so thanks a lot. Couple of serious problems though, my mic no longer works (people can't hear anything when I call them) and when I play music on my phone the sound comes out of the earpiece speaker and nothing comes out of the speakers on the bottom of the phone. Restored backup that I took before flashing and no more problems so think I have narrowed it down to this alone.

I guess I could live without it but would rather not as I couldn't believe the difference it made to the audio quality and depth. Anyone know what is causing this problem?

I´ll post later on the sound configuration.

[ONE Themes and Apps] itsamoreh:
Just a question

I used Viper on 4.4.4 but my new 5.1 ROM, Euphoria comes with CM12's AudioFX which works for me. Is Viper simply better because of all the customizations? Do you guys use all of the options? I'm only asking because when I used it I only used the Viper BASS and Viper Clarity.
[ONE Themes and Apps] neotoky:
That's what I also use for viper. I can't stand that with maxxaudio when you turn it on it turns everything on. I want the equalizer with a separate off setting.
[ONE Themes and Apps] neotoky:
This is not working for me at all even with selinux on permissive on cos 12.

Edit: works I forget that selinux resets after reboots and have to go back to the app

Hi Everyone,

I have a Oneplus one with kitkat 4.4.4 (Cyanogen OS 11.0-XNPH05Q) on it.

I would like to try this Viper4Android and install it on my mobile phone.

I don't have a lot of experience with the Android's world and I need to know what exactly I have to do.

Could you please help me?

Thanks.
[ONE Themes and Apps] davebugyi:
On 4.4 is fairly easy. Download the latest 2.3.4.0 .apk (for ANDROID 4 - because there is also one for older android versions like 2.3)

Install the .apk (check Unknown sources in settings) from a file manager

Open V4A app - it will ask for installing drivers - click yes, select quality and reboot

After reboot enter the app, and play around with the settings or search XDA for presets and files.
[ONE Themes and Apps] devbobby:
Why are there 2 apks in the zip file?

Thanks
[ONE Themes and Apps] davebugyi:
Well, I told you earlier. One is for Android 4+ and one is for older android versions. You need the new one.
[ONE Themes and Apps] devbobby:
I see the "ViPER4Android_FX_A2.3" apk

and

ViPER4Android_FX_A4.x

Therefore, the second one should be for my Oneplus with kitkat. Did I get it right?

Just another question.

Does it work with any music player app? Did I somehow need to set it properly in any music-player app like N7 player or Poweramp?

Thanks again.
[ONE Themes and Apps] davebugyi:
Right. 4.x is the correct file

It should work with any music player app, but maybe you need to disable poweramp's buit-in EQ.

If you flashed the build.prop fix.zip, you need to restore your original build.prop to boot up the ROM. Dirty flash of your current ROM may also help.
