How to install DTS Sound mod

Issues
U tell me (got no issues with it, pretty stable)
​

Support​

I only support Custom ROMs... It is working on MIUI but I won't fix issues for MIUI! (As example Kernelversion shows unavailable)
Also it's confirmed to work too on Mi6x (Wayne) but i won't support it officially because i don't own this device!​

Flashing​

Make sure u backup ur current Kernel before flashing! I'm not taking responsibility for any damage!
If you installed a custom Kernel before please flash the boot.img of the currently installed ROM or dirty flash the ROM (I prefer dirty flashing)
Then just flash the zip file through TWRP...
And have fun with the full "IceCold Experience"

How could u test? Anykernel will not install on wayne, it will cancel...
I didn't made the installer script compatible with wayne yet

Edit: Uploaded a stable version with some patches i've got working, should be smooth.
Also added wayne in the installer script so wayne users can flash it!
Keep in mind I don't officially support it

wired problem on wayne after reboot audio port is not working

As I mentioned I don't support this device. Try wiping cache and dalvik.
Reboot again won't fix?
Normal audio working?
BT-Audio working?
Otherwise I can't help u because i only have whyred and not wayne.

I think it won't help but it's worth a try i think, else u have to switch kernel (eventually I will find a fix for it later)
