Hi, I need help.

I installed V4A, but couldn't notice any effects, so I uninstalled it following Op's directions and re-copied my build.prop back to the system.... Now my phone is stuck in bootloop...

I think I messed up when I recopied the build.prop back...

My phone is the LG Optimus F3. Yes, it was rooted and was on the latest possible F3 update.

Not working - CM12 (CONDOR)

I followed every step. when I install apk and open the app it asks to install driver, I press ok then it ask to reboot and when I reboot the phone and open the app it again asks to install driver and again and again and again and again the whole process repeat.

No xposed. I have busybox installed.

Hi Community,

I am using Viper4Android for a month. Version. 2.3.4.0. Galaxy S3 with Cyanogenmod 11, latest nightly(s).

I like this app very much, but i have following problem: Sometimes, mostly when using Opera for Android ( and also other apps sometimes), the Viper4Android app crashes. When i look into Settings->Apps->Running Viper4Android is restarting. And always when this happen, three other apps crashing and restarting too (always the same three: aCalendar+, Dropbox and Amazon).

"Force enable V4A" don't solve this problem.

Any ideas?

And another question: Cynogenmod has a build-in DSP Manager (but it doesn't work for me, don't idea why). Should i disable it (e. g. frozing with Titanium Backup) while using Viper4Android to avoid conflicts?

Thank you very much for your help!!

Edit: It seems as i could solve my problem by copying the apk to /system/data :)

Reading FAQ can help.:o

How can I get Viper4Android to work on LG P769 wired headphones?

I've installed Viper4Android version 2.3.4.0(FX). I believe it installs the compatible driver on its own. It works fine on my bluetooth headphones but when I plug in my wired headphones I get no effect changes. I check the driver status when the bluetooth headphones are connected and the settings are as follow:

Driver Version: 2.3.4.0

NEON Enabled: Yes

Enabled:Yes

Audio Format: Supported

Processing: Yes

Sampling: Rate: 44100

I get the following when the wired headphones are plugged in:

Driver Version: 2.3.4.0

NEON Enabled: Yes

Enabled:Yes

Audio Format: Supported

Processing: No

Sampling: Rate: 44100

I've tried the three different driver settings as well as the Compatible Mode. I moved the apk from /data/app to /system/app because I read on another forum that this solved a similar problem for this person but I still can't get the wired headphones to work with this app. I would really like to get this solved, the sound is awsome on the bluetooth headset! My phone is rooted but the rom is stock LG P76920h. The only things I've installed are BusyBox and Exposed Framework with a few modules.

But when I check "Driver Status", it is NOT Enabled.

I tried "Compatible Mode", Rebooted, but No Joy!

Any ideas??? Again, I'm running KitKat 4.4.4

I did set the Permissions on it properly.

I know that XHiFi has been discountinued,

Hi ,

I have been using Viper4Android for about 2 months now. I love this app and it worked properly since today. I've always used Spotify as a Player and it just worked fine . However, when I start a track it plays the track for 1 sec or so , then u cant hear any music for another sec and afrer that it continues with the song WITHOUT the equalizer of Viper4Android. In other words, v4a doesnt work anymore for me with Spotify. Does anyone else encountered the same problem until recently ? any hints what I could do besides that ?

thanks in advance

I'm still having an issue with XHiFi in KK. I got it to see it as a System App and to install the driver, but when I check "Driver Status", it says "No" next to "Enabled".

But what got me this far and what's fixed a couple of different problems for people, is to run "SELinux" and set it to "Permissive".

You can find it on "1Mobile Market" and if you need me to, I can just upload it to my DropBox and create a link for you, or if you PM me with an email address, email it to you.

Maybe it'll fix you up? From what I could see, it can't do any harm. I believe at worst, it just won't work.

[Android Q&A, Help & Troubleshooting] Zeuszoos:
I've got a Zip that has a bunch of files in it and it's supposed to fix Lollipop issues (with SELinux, I think).

I don't know if it's a Zip that you install thru Recovery, or if you manually UnZip it and put the files where they go.

You guys can have the Zip if you want it (and SELinux) and I'm sorry I couldn't be more helpful, but I don't run Lollipop, so I haven't messed with it. I just grabbed it when I saw it, figuring maybe somebody else could use it. :)

---------- Post added at 12:59 AM ---------- Previous post was at 12:45 AM ----------

I'm not running Lollipop, so I'm sorry, but I can't help much.

But on SELinux, it says that in mine too, yet as soon as I ran SELinux, I was able to install XHiFi as a System App. And I had tried quite a bit! :)

Plus it does say that it was succesful. But maybe it does do it, but just doesn't "stick"?

I'm not even convinced that SELinux is even needed beyond the initial setup of V4A. No idea, really. :)

Nexus 6 Aux output not working

Hallo,

i'm using VIPER4Android 2.3.4.0 (FX) on a Nexus 6 with Chroma 12/5 Rom. If i plug a headphone everything is fine (sound is coming out the headphone), but if i try to plug an aux cable the sound is played over the phone speaker and not outputted over the jack!

I reflashed the rom and did not install VIPER4Android and the sound is played correctly when aux is plugged in. The sound is streamed over the jack.

So I think the driver is making some changes and the aux cable is not recognized when plugged in.

Is there a option to force the audio stream to go out to the jack? Or something else?

Thanks

So, basically V4A turns off when i run any other app while listening music (Spotify), then sometimes it re-enables itself after 3 seconds or so, sometimes it doesn't, so i have to launch V4A settings app manually to turn it on. What's the issue? Do you need some logs for that?

Hey, I'm having a bit of trouble installing V4A on Cyanogenmod 12.1 and getting it working with USB audio.
