1. Copied v4a app to system/priv-apps/...
2. Frozen sound alive and adapt sound service
3. Rebooted

Any help appreciated.

Viper works fantastic on device.
These are correct steps :
First you need PERMISSIVE kernel, otherwise it won't work.
You need to DELETE not to freeze sound alive and adapt sound.
In build.prop find the lines or add them as follows ;
Ipa.decode=false
tunnel.decode=false
lpa.use-stagefright=false.
Push Viper apk in private apps.
Set apk permission to
rw-r-r
rw-r
Reboot device.
Run Viper again and follow instructions.

Copying and freezing some apps cant make it work properly man. Viper4Android needs lots of frameworks, lib files, effect and permission files etc(build.prob additions).. So; Audax Rom's sound mod is working without any problem(Viper+Dolby Atmos). After flashing the rom you dont even need to install drivers for V4A!!

thx for your reply!
as far as i know the build.prop edits are no more necessary in lollipop, the were needed in kitkat.
also the permissive kernel is no longer a requirement, as systemless root and adding the vfa policy fix would work with lollipop stock kernels.
but just to get sure, i tried your recommendations to the point, but with the same result as with my setup:
all seems to be right, but in driver status it says
NEON enabled: Yes
Enabled: Yes
Status: Normal
Audio Format: Supported
Processing: No
Sampling Rate: 48000
the strange thing is: I only get NEON enabled when installing the driver per zip flash, otherwise vfa would install a non neon driver.
i use vfa since years, and i never went into such problems as with samsung 5.1.1...
any ideas what i'm doing wrong??
Hey, my H7 is rooted, and running Emui 4.0 (B320).
I love the phone but i think the sound volume is just too low. I've download Xtreme music package as long as viper4android, but the volume is still too low.
I've try to modify mixer_paths.xml, like i did with my galaxys, but i can't find it with root browser on this phone.
I've tried to modify local_prop in CUST/hw/Eu/prop to remove the volume limitation but there is not the line ro.config.hw.security_volume as it is on other phones. (tutorial for other phones including this technique here: http://forum.xda-developers.com/showthread.php?t=2531673 )
There is no codec folder either, so i can't try the solution by removing it.
There is an Audio folder tho, under system/etc/ and within it, there are a dozen of folder, and one called Hi6402 containing a lot of mixer_paths files like CARRERA DAVINCE GRACE etc, and a lot of mixer_volumes files with the same name. Both have a default version.
There is no line allowing to modify the volume in the mixer_paths.xml file, but there are plenty in the mixer volume one. Could this be it? I don't know what to change, as all the others file have this lines too, and there are plenty of them.
Thanks for the help.
There is a file with a volume security in HW_OEM/PROP, but changing the values didnt change a thing. I'm doing further investigations.
Dude, you're going to break your ears![emoji14]I don't know about managing maximum volume but quick question : you successfully installed Viper4Android?? Last time I tried, drivers won't install correctly and nothing changed when I activated equalizers..

Haha don't worry i'm used to it. Did you instal busybox and/or selinux? They are both needed for the application to work.
Try to download a different version of the application if you still can't install drivers, and check if you are properly rooted.
I couldn't get V4A working either.. Can you tell how it is done? I'm on B320 rooted and busybox installed. I downloaded and installed the Marshmallow-version of the V4A. Do I have to enable it somehow in honor's audio settings because there seems not to be a place where i can choose what audio effect to use? I have also tried several audio players, but does it matter which to use? Driver status says "abnormal" so that's probably the problem..?

Search in this forum for SElinuxModeChanger app.
Sent from PLK-TL01H
Saw a dual thread speaker thread, but I'll build was missing. Anyone figure out the adjustments needed? Have gotten exposed, lp working, audio mode by Devine beats 7.0 with the dd+ add on to work. Have to have se Linux changer to enable permissive. Anyone who hasn't gotten to work, noticed in flashfire when you run zip if you unchecked mount read/write in last option it won't stick. But with it enabled to mount system read/write sticks and no problems. Black player music aPk on same thread works also. Just noto eq engine. Marshmallow SD fix in exposed will fix write access to SD card.
Regarding the sound mod by @sshafranko hope someone knows what needs to be changed.
I have the mixer paths file that was for the note 5 but it didn't work on our s7edge.

Here's the link for SEC Linux mode changer 3.2, Just install it and make sure give it root access when SU asks. There is a block to check to enable notification on mode change. I would check that off. Then you will see permissive and enforcing. You want to have permissive grayed out and enforcing in bold black. Which is done by pressing permissive, you will then see a notification that the kernel is now permissive. I've been checking multiple sound modes out. I would try Extreme beats 7.5.9 by android experts. It's in Android software thread. Also there is a add on for dolby digital. Flash Extreme beats followed by SD if your want to install that also. After boot you will have the extreme beats app looks like beats audio app and viper4android. Sound mood is unreal by far best of any out there tried them all. I'm a flash adrive. If you need more help let me know

Hey anyone know how to boost the volume on s5? I'm not very tech savvy so if you could send me a link to a step by step guide. It appears from my searching I have to root my phone or possibly install a rom. any thoughts? Help!
There are 2 ways that I know of and both need root.
1) a music app (available on XDA) called viper4android has a setting that will give a 6dB boost.
2) adjusting an XML file within android itself (potentially risky).

Thanks :good: . I actually did look at the thread before, but had the impression that the GSI Treble roms were of the ASOP variant, contrary to the note: 'NOTE: This works only on CAF based custom roms. It doesn't work on AOSP.'
Am I wrong, or is it the note that does not apply in this case?
it looks like not both ways aren't working for 9.0 Havoc.
we need better solutions.
I tried these solutions on the Lenovo Z5 pro GT, but the Phone won't recognise any bluetooth IEM's. The sound keeps playing over the speaker. Does anyone have a solution?
When I change vendor to r/w it goes back to file system read only and I can't save the build.prop file afterwards
If someone was able to make it work can you please show me the build.prop permissions!!
this ROM is awesome. but there's a problem. my BT headphone no sound.
in developer options, "disable bluetooth A2DP hardware" can't be turned off. any solution?
And for xiaomi devices?
What is the apk that I have to delete if my device had miui?
in all the GSI images i installed audio BT is not working.
And BluetoothResCommon.apk is not in that path, why ?
build.prop is there but there is no "persist.vendor.bt.a2dp_offload_cap=sbc-aac-aptx-aptXHD" entry
Any help to fix bluetooth for this case ? I can pair, to headphones connect, for a moment seems to work, but finally audio get played in the phone itself.

Overcame the lack of sound in BT headphones on android 10 by replacing system / lib / libbluetooth.so and system / lib64 / libbluetooth.so with stock firmware

by any chance have you experianced slow command response with ADB? I just install win10 1803 pro and its so so slow to even run adb devices command. does it make a difference if my device is running GSI Phh A11?
Did the trick for me! Thank you

It can be done with root or in TWRP.
But now most phones have aptx-aptXHD support in original firmware, so there's a high possibility you don't need this step. By the way, it is not worth it to fix A2DP though, cause for now it's almost not possible (at lease I didn't solution) to fix bluetooth in call and A2DP offload at the same time. For me bluetooth in call is more important, and there's actually no side effect to turn off A2DP offload as far as I understand.
Anyways, to make bluetooth in call and Aptx (of course others like LDAC) both work, you'll need to:
1. remove /vendor/overlay/BluetoothResCommon.apk (if presented) (if presented and deleted, do a factory reset)
2. remove /vendor/etc/a2dp_audio_policy_configuration.xml
3. Enable "Force-disable A2DP offload" in phh settings
4. Enable "use alternate audio policy" in phh settings if your volume adjustment have any problems (if you got multi ones in different feature category, try different combination until it behave normally)(may require reboot)
5. flash Magisk module "aptx-HD-magisk-10_arm.arm64.zip" to fix aptx support
Now both sbc-aac-aptx-aptXHD-LDAC and bluetooth in call should work. Tested on 2 Qualcomm setups recently with phh android 12 based rom.
Hope this could help you and others having same issues.

Tho Xiaomi's MIUI really modified the whole aosp crazyly,but the device itself is still treble-compactible
the file is called MIUIbluetoothres.apk(probably,on miui 12.5's vendor)
BUT you dont need to del it.
To Fix: TURN ON "force disable a2dp offload" in phh treble settings.
that's it.(worked on redmi 10a.(MTK))
(ps: actually aptx is a qcom thing so it probably wont work on mtk devices.)
