Selinux permissive

Hey xda I'm looking for a kernel for PAC Man ROM that is selinux permissive to enable touch screen compatibility with my appradio 3. I've tried the selinux mode changer but it doesn't seem to do any thing except set a notification that it set selinux to permissive.
Abby suggestions it there?

Have you made sure that it doesn't change anything, you can check the selinux status under Settings>About Phone. I personally have never had this problem. also can you tell me why you need to change it to permissive.

Thanks for your reply. What I mean about nothing changes is when I check the status in settings>about phone after setting permissive mode with the selinux mode changer app and rebooting like it requests it still says enforceing. as to why I want to change it, I said before I am trying to get the touch interface to work on my pioneer appradio 3 head unit. I can mirror but touch doesn't work on the head unit. I have read in the appradio forum that you have to set SeLinux to permissive in order to accomplish this. I was hoping that some one with knowledge of custom kernels would be able to shed some light on this since it seems that Pac Man is set to enforcing by default. Also I have read that other kernels for other devices had the permissive mode set. I am so close to having this functionality it is getting frustrating, but I like the features that pac man brings to the table so I don't really want to switch. at this point.

Ok well when i needed to do this i would always use the app described here. also its not that PAC ROM does this intentionally, in fact it was google who made 4.4.2 selinux set to enforcing, and its because of this that most if not all kernels for 4.4.2 have selinux set to enforcing.

MIUI Music player for Oneplus three

Hi all, I've recently upgraded to the Oneplus three but i'm not able to get the same quality audio output using Mi in ear pro headphones or the Pistons which i was getting using mi4. Is there any way to port the MIUI Music player to OP3 so that i can use the sound enhancer specially designed for Mi branded ones(i've quite a collection of the Mi branded headphones). Any help would be appreciated.

How about viper4android?

viper4android would be great but i soft bricked my phone by flashing viper yesterday... where can i find a functional viper4android version?

viper4android is great but the MIUI MUSIC player has been greatly optimised for use with the headphones of their brand. Combination of the miui music player and viper4android would be absolutely amazing.

I should get the device on Monday so I'll put together a version that will work properly on the OP3.
You usually have to make a tweak to the audio policy to make it work with apps other than play music.
I don't get how you managed to soft brick unless you flashed a version with system modifications designed for a different device.

Thank you so much!
Yeah what did I do?! First I tried the official apk in permissive kernel mode. But the driver status was abnormal and it didn't work. Then I flashed xtrememusic mod with v4a through TWRP. It was running great but battery life was really worse (more than normal for the v4a) the camera couldn't take pics anyone and some other errors occurred.

The abnormal driver status is due to the audiopolicy.
If you want to try yourself you can edit /system/etc/audio_policy.conf and remove the section relating to deep buffer. (It's usually about 10 lines)
Reboot and the driver status should change to normal and start working

I would like to test it, really but the other problem is, you can't roll back a twrp backup in twrp beta - I tried by changing system partition writable but the phone doesn't boot after backup roll back

I got my info wrong yesterday.
The deep buffer prevents processing in apps other than play music.
The unusual driver status is because of having enforcing selinux.
You either change to permissive or you can also use the following su.d script to allow processing while enforcing.
/system/su.d/V4A.sh
Code:
/system/xbin/supolicy --live "allow mediaserver mediaserver_tmpfs:file { read write execute };"

I also tried to install V4A on my oneplus 3 with the following steps.
1. Set selinux to permissive by following padhu1989's init.d workaround (Selinxmod not working in oneplus 3).
2. Install V4A app+driver and reboot.
However, the driver status shows processing = no, and sound effects not working (Other driver status are all yes and normal).
Could it be due the deep buffer matter you mention in the above post?

[Module] Stereo Sound Mod for OP5T [N-O]

Just wanna share simple modification for our beloved 5T.
This module allows the earpiece to be used as speaker, and enable true stereo mode.
*np: flash at ur own risk
Instruction:
1. flash via magisk manager
2. you're good to go
if you use the version with OP5TSpeakerCtrl app, please read this
chdloc said:
"Mono" mode -- the main loudspeaker's volume is set to maximum (stock behavior) and it is fed with a downmix of the left and right channels (also stock behavior)
"Stereo" mode -- the main loudspeaker's volume is lowered to match the volume of the earpiece and is fed with the right audio channel (true stereo)
In "Adaptive" mode, stereo operation is applied when the screen is on and mono when the screen is off. In "Stock" mode (I should have named it "Manual"), the mode of operation does not change automatically, but is manually selected by tapping the "Mono" and "Stereo" buttons in the app's permanent notification.

I was going to try this on 8.1 Omni, but it would probably break the sound all together since the mixer path file is completely different.
What lines do you edit to change it? I can just do my own editing.

Is this for headset or speaker?

Lol really now?

Works great!
Only small niggle: it is possible to adjust the volume of the two speakers? As of now the sound coming from the earpiece is lower (which I can understand as it most probably is a much smaller speaker) but if it would be possible to lower the volume coming from the main speaker the balance would be much improved
But for now: much better already :good:

[GUIDE] Get perfect surround sound from phone speaker with dolby atmos and viper4a

INTRODUCTION
*WARNING USE AT YOUR OWN RISKS*
Though the poco F1 has stereo speakers, the earpiece is sort of weak in comparison to bottom one and so the sound quality falls short when compared to other phones with dual speakers. With this guide, you can make your phone sound much balanced, immersive and better. Basically what it does is increase audio coming out from earpiece by using viper in combination with Dolby. Also this does not increases sound from earpiece beyond max level but instead reduces volume of bottom speaker slightly so it will not damage your speaker
REQUIREMENTS
Any custom rom with magisk and permissive SElinux
STEPS
1. Flash permissiver zip or use SElinux switcher to make SElinux permissive for Dolby module to work
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then reboot and test if Viper4A is successfully installed and working
4. Flash ACDB zip first in magisk then flash dolby audio zip and then reboot. You should now have moto audio app installed and working.
5. Put XHR WideFX irs file to main storage/Android/data/com.pittvandewitt.viperfx/files/Kernel
6. In Viper, enable convolver then choose the file to enable it.
7. For dolby, the default settings (smart audio) is great but personally I use film mode with surround sound and volume leveller enabled.
I have tested this in evolution X rom and it should work in other roms also. For stock rom it may require a custom kernel. If Dolby Atmos doesn't work then try Dolby Digital instead.
If you face issues like Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it. If dolby app force closes then reflash it and clear catch after installation

On first choose no then select patch (new logic) then again choose no for notification helper and select remove volume listener library
Even if you skipped it wouldn't matter much because ACP is used just to fix audio not working in some apps and it does slightly enhances audio quality and volume.
For usb dac you can choose yes if you don't use wired headphones from usb c port
For viper though, you shouldn't get that warning
Maybe problem could be in your twrp
Manually mount system in twrp then try flashing again. If it didn't work you may have to reflash recovery
But you said that it is working? Did you tested the audio also? Because the magisk module only installs the app and some configs. The drivers are installed from recovery. You can also tap on the chip like icon button in viper and it should show the driver info and enabled as yes properly

Yes even tho i got warning, but it properly working. I already use it like 6hour, all is working fine.
but when i installing Dolby Atmos, i got bootloop and force me to bootloader. but when restarting phone i can access twrp, just removing them in module via twrp everything is back normal.
but i think it doesnt support latest MIUI Global 11.0.4 ? i got stock MIUI11
Anyway, after wiping module via twrp my viper now doesnt have driver on the app. i already doing the exactly same step 1 - 3 to install viper and it didnt work rightnow. driver still doesnt work even tho i tried installing this many times.
I already go to viper4x thread, someone say need to overwrite 2 file ( post-fs-data.sh & sepolicy.rule ) but still doesnt fix driver.
maybe you know how to ? :laugh:

Dolby Atmos is known to not work as of now in stock kernel or roms for many devices as it is still under development. You can try dolby digital instead
But are you getting the same error on twrp for viper? With system not mounting?

Anybody make it work with Pixel Experience ROM 10.0'
Hi, I want to install it and I have Pixel Experience ROM 10.0 Official. I'm curious if anybody successfully instaled it on this ROM.
Thanks

But with this guide, you can make your phone sound much balanced, immersive and better with Dolby Atmos and Viper. It actually feels like if the sound is coming towards you and not from the side
This requires the XHR WideFX irs. This is the only one I found till now which worked so perfectly with atmos after testing 500+ irs files.
REQUIREMENTS
Any android 9+ rom with magisk and permissive SElinux
STEPS
1. Install Audio Compability Patch first in magisk then reboot
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then again reboot and confirm if Viper4A is successfully installed and working
4. Flash Dolby Atmos zip file in magisk (you can download it from guitardedhero's post also for new version) and reboot. You should have both Dolby Atmos and Viper4A working at this point
5. Now to get that stereo sound effect, put XHR WideFX irs file in main storage/Viper4Android/Kernel folder
6. Open Viper and enable convolver then choose the same.
You can now test the sound and enjoy the stereo sound effect. It is best for gaming or while watching movies.
I have tested this in evolution X 4.0 rom and it should work in other roms also but I am not sure for OOS. For stock rom it may require a custom kernel. If it works in your rom then please comment down below so that others could also know it.
If you face issues regarding Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it.

I have personally tested it in PE pie and Evo X 10 version. But this one should work in any android 10 based custom rom as long as you don't have any other audio mods installed conflicting it or else you may require AML also.

Viper is working fine but after installing Dolby Atmos and rebooting i am stuck at Fastboot, had to remove the dolby module.
Is this related to Miui 11 or some selinux problem??
Please suggest some workaround.

Will this work on miui 11?

Looks like it doesn't work in miui as of now
But you can try dolby digital instead which is also good. Dolby Atmos is still like an early release and currently only works in custom roms and kernels
But remember to choose the IRS file in viper. That makes the earpiece work more balanced. Dolby is just to further enhance the sound quality.

Flash permissiver zip file to fix it
I am also currently on PE+ latest and have not encountered any such issues
My recommendation is use Dolby digital instead as it is more stable (v7.2)
