Go to search type in Samsung Galaxy Mega you have lots of stuff to mess with simple but first things first you won't need to change your kernel to permissive because your on kit kat if you want to get both of them working Google 'how to install v4a using Lucky Patcher

Whoever is making the flashable zips that replace the entire audio_policy.conf file in ROMs, I found an alternative way which comments out the deep_buffer lines via sed command instead of replacing the file (as it may change in ROMs such as CM.) I have my own addon.d script that backs up what I would like it to, along with applying some changes for V4A functionality.

This is what I have in my addon.d script (placed under the post-restore section) to search and comment out the deep_buffer lines:

Code:

[COLOR="Green"]# audio_policy.conf edits for V4A compatibility[/COLOR] sed -i '/deep_buffer {/,/}/s/^/#/' /system/etc/audio_policy.conf

Once the script finishes what it needs to do, the deep_buffer lines will look like so:

Code:

# deep_buffer { # sampling_rates 8000|11025|12000|16000|22050|24000|32000|44100|48000 # channel_masks AUDIO_CHANNEL_OUT_STEREO # formats AUDIO_FORMAT_PCM_16_BIT # devices AUDIO_DEVICE_OUT_EARPIECE|AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_WIRED_HEADSET|AUDIO_DEVICE_OUT_WIRED_HEADPHONE|AUDIO_DEVICE_OUT_ALL_SCO|AUDIO_DEVICE_OUT_AUX_DIGITAL|AUDIO_DEVICE_OUT_PROXY # flags AUDIO_OUTPUT_FLAG_DEEP_BUFFER # }

And what I have in my addon.d script (also placed under the post-restore section) to add to build.prop

Code:

[COLOR="Green"]# build.prop edits for V4A functionality[/COLOR] echo "lpa.decode=false" >> /system/build.prop; echo "lpa.releaselock=false" >> /system/build.prop; echo "lpa.use-stagefright=false" >> /system/build.prop; echo "tunnel.decode=false" >> /system/build.prop;

Hopefully these will be of use to some who also create their own addon.d scripts.

I added the policy to my test zips. Can you take a peak at the add.on script I use in my zips and see if this looks correct? I've attached it below.

BTW I find that with the deep buffer edits the build prop changes are not needed. Or at least no one has come back into my thread saying Viper stopped for them. Dozens of users from different devices are using my zips.

Go to post #4301 (page 431) of the official v4a thread

Thank you! I just have to fully disable DVC (since I didn't disabled it entirely before) on Poweramp, and now V4A works! Thank you so much! :good:

Now back on making Anime Zooper Widgets! BD

:good:

Sure enough it works as intended and in the right place

Here on my Nexus 5 running CM12.1 Nightly (CAF Version) I've had a few moments where V4A would not kick in after a while even with AudioFX removed completely. For example: it'll work fine before I get to class, but when I get out 2 hours later and continue playing my music, it wasn't processing until I rebooted. For me the commenting out of deep buffer seemed to have fixed it for me on CM CAF, unless it's the stupid memory leak in Lollipop causing it.

Awesome man. If you don't mind I'd like to add that to the zip and remove the edited .conf file. I had seen myfluxi's commits earlier this week about him editing the audio_policy.conf file for hammerhead and was wondering how that would come into play since so many ROMs use CM as their base. Your method works much cleaner.

Just install below apk.

I did install it and run it and the Notification says it did it. Weird result otherwise though! But B4 that, it keeps running at Startup, setting it to Permissive. Is it supposed to do that? I mean, does it need to? Or once set, it stays set and I can take it out of Startup?

Anyway, after running this utility, I was able to get my phone to see it as a System App (Yaaay!).

However, when I went to run the XHiFi app (after setting my phone to it), my screen went black and stayed black. I could flip it to the background though. I tried rebooting, same result. I then went to Kill the process, which didn't work, but after 3 tries, XHiFi prompted for SU access. Weird, huh?

Anyway, after that and rebooting, the app did come up fine. I installed the sriver, Enabled XHiFi in the apps' settings and rebooted.

When it came up, I opened the XHiFi app and checked "Driver Status", but it is not Enabled. Tried Uninstall/Reinstal and a couple of other things, but no luck.

I'll have to figure out what's going on, but I thought you might find this bit interesting.

Thank you for the app though! I got farther in a couple of minutes, than I have for the last 3 days! And that, contrary to popular belief, that was indeed including lots of reading.

Thanks again!!!

Have you uninstalled/freezed Samsung Music player and disabled SoundAlive as discribed in in the OP?

Ok, so I am going to try this once more. There is a lot of yelling in here about this topic, i have seen, which is not very nice. I know how to research. I READ THE OP. i know how to tear my phone down to KK NCE and then back up to whatever. So as my signature says, i have a wonderful locked BL ATT S5 (G900A). As you all have heard many times (i did research), it does not seem to work on our phones. i have heard this is due to the fact that we lost control over Permissive mode going to the OC4 (5.0) kernel. IS THIS TRUE? please answer. if this IS the answer then i will go away. if this is not the answer, does anyone know how to fix it? Yes i read the post about the 3 (well really 2 zips). no i have not tried it. yes i have a backup. many and more than one way to restore, but still i am asking. So i dont know what the samsung music player is, but if it is MUSIC, then it is frozen. SoundAlive, whatever that is, is frozen. app installs. driver installs. install and run at boot the useless SeLinux Mode changer app and set to Permissive. Reboot. Start playing song using Poweramp. Open Viper, setup, and soon as enable, POOF, MUSIC PAUSES AND STOPS PLAYING, but music can be unpaused and starts playing after disabling Viper. Is there any direction or is the answer Permissive mode is needed? They are working on it now, but who knows when it will be fixed. Many of you are very lucky to have an unlocked phone to do whatever you want with. WE cant replace the bootloader or Kernel to whatever we want to. :crying:

SO THANK YOU FOR INDULGING ME IF YOU GOT DOWN TO HERE AND DO NO YELL PLEASE. AGAIN, I TRIED MANY TIMES TO FIND THE ANSWER. THANK YOU ALL.

You're more than welcome to add it. It's at least something I can give back to the community.

I just cleaned several pages of crap from this thread. Please stick to the topic at hand. If you cannot do this without arguing & bickering then perhaps XDA is not the place for you.

I know that you'll probably think this a stupid question, but I ran this utility and it appeared to work fine. But it runs every time my phones boots up and my question is; Does it need to run and set to "Permissive Mode" every time my phone starts up? Or is it a "run once and it's done" utility and I don't need it any more?

I appreciate your time. Thank you in advance for your patience with me.

My apologies Moderator, for my part in any arguments here in your thread. It won't happen again.

I don't use xHiFi with v4afx anymore but I remember it always said Not Enabled in Driver Status unless music was actually playing.

I use this and SuperSU on my tablet, when my device is powered on, I just get a toast message saying it's been granted super user permissions and when I check in settings it's permissive right from the start. If you're having something different, maybe ask on the thread I linked?

From what I know, some kernels usually set enforcing mode on startup, especially Samsung phones. It depends on the manufacturer.

As for "arguments", there's bound to be some guy who can't be bothered to use the search button and ask a redundant question that has been answered a million times.

I'm running cyanogenmod 12s Android 5.0.2 on my oneplus one

Got selinux set to permissive and nuplayer enabled

I wanna make v4a work with PlayerPro, it used to work but after the update it doesn't anymore.
Tested with Google player and shuttle player and it works, it doesn't for player pro and power amp...maybe it has something to do with the built in audio fx/maxx audio which also doesnt work, even when running compatible mode nothing works.. Rly getting frustrated here cuz in my setting I can't chose which audio fx I wanna use

need v4a back :'( pls help

I think you may be thinking of the one that says; "Processing". The "Enabled" one should say "Yes" if the driver is working.

I'm extremely familiar with v4afx and v4axhifi, when using both on my devices v4afx will always say enabled with no music playing, however, xhifi always showed not enabled with no music playing. Play some music and xhifi is suddenly enabled and processing. I don't post much but when I do it's with plenty of confidence, otherwise I'll let someone else post the necessary/requested information.

I was thinking of FX, no doubt. And based on your word, I set it all for XHiFi and rebooted. Then I loaded the music player I usually use (Music Folder Player Full, by ZorillaSoft), started playing a song, flipped back and checked out XHiFi and sure enough, it said; "Enabled"! You were right!

So apparently, I've actually had it working since running the "SELinux2" Apk and just didn't know it! <lol>

I want to say a sincere and very big; "Thank You!". I really appreciate your help! I really do! Without your knowledge of this fact, I'd still be pulling my hair out, probably for some time to come et!

May I ask you just one question, please? If I am using XHiFi, do I need to even have FX on my device? Thank You!

I would not use xhifi alone as I depend on the covolver function in v4afx, v4afx will always be mandatory for me. Also mandatory for me is ExtremeBeats 4.1, also found in this forum section. V4afx and ExtremeBeats 4.1 has been the best combo I've ever tried with other combinations of mods. I used xhifi along with v4a fx and ExtremeBeats for a long time but I definitely noticed an improvement disabling xhifi. In my setup, I noticed that xhifi simply added too much " noise" to the overall audio.

And you're very welcome, with hobbies like this it's easy for us to create our own "problems" lol.
