[MOD][SOUND][BUG FIX] Z1 Lollipop viper4android sound

[grimreaper3439]

This is a sound mod for stock Lollipop ROM and is tested on c6906 but should work on c6903 and c6902 models. All scripts and files are not mine. All credits go to their owners, I just made the tutorial for you to enjoy bug free good sound on your z1.

Note: this will set your SElinux to permissive, if you don't know what it means research a little. It's a security lock on your phone to make it more secure and it will disable it.

1. Install busybox on your phone.
2. Install SELinux apk and open it to set kernel to permissive.
3. Boot to recovery and flash "testlolliviper.zip", no need to wipe anything.
4. Open Viper 4 android app on your app drawer and install drivers then reboot.
5. Enjoy your bug free Lollipop improved sound.

Note: SELinux must be kept as permissive for Viper mod to work.

Script credits go to their respective owners, I do not own any of the mods. I just made this tutorial since no one has done one for our z1.

That's strange, it doesn't happen to me. Try to clear AudioSettings data and see if it keeps FCing.

Maybe it cannot be functional with dseehx mod??

Though i found a workaround
Use standard 2.3.4
trigering the dseehx (both enable/disable)will enable v4a to work for few seconds.
Enable DSEE-HX..... some seconds later v4a dead right?
now keep the music playing
now press home to leave music-> enter music again->quit->enter->quit->enter->quit
repeat a few times v4a will suddenly work (forever) when u leave walkman by pressing home = =

Yeah, that's the problem. It's barely stable on stock I forgot to mention that.

^last thread updated
Though with v4a, the effect of dseehx is very obvious

I got it to work too, and I didn't have any problems wei ugh them being both enabled. Might be a file you have or a line that interferes. But it's good you got it to work.

Does doing so re-enable usb audio support?
