Unofficial CM12.1 some root apps work some not

Hello guys, I am running unofficial CM12.1 on my LENOVO A6000 plus. It's running really very good in terms of performance as well as battery backup, but I am facing some problems.. Even though I have allowed root access to 'apps and adb', some root apps are not working while some are. For ex. Greenify is working great as well as root explorer, in there, I can mount system rw temporarily and delete or add something in system folder. But I can't do the same thing with built in CyanogenMod file manager. Rom toolbox is also not working. I have previously used Xperia U, rooted, bootloader unlocked, running CM11 or stock rom and never had such a problem.. Even on A6000 plus, running stock rom gave me full root access. A lot of searching only reveals me that CM12.1 comes pre rooted. Then why root is not working for me? In terminal emulator if I type 'su', $ changes to #, that means I have root access. My thinking says, it might be because my root partition is not mounted as rw by default that's why I am facing these problem.. What you, more experienced guys think?

No sound & some games only loading their launchers

The First time i open a game the sound usually works. But if I quit and open another it won't work and either has no sound, or super stuttering sound then drops.

Also, the controller only works in games like team fortress 2 hl2, cs go, etc once in actually in the game. Also games like far cry 3 simply load u play, but don't actually launch the game.

Shield TV + windows 10 660 ti
I updated sound card too.

I'm pretty sure that I'm on the newest beta version, but I'm not what version is the newest for both the shield android app and the GeForce experience?

Is there anything else I can try? I'd really like to get this working.

HA2100 dual core wifi issue and some questions

Hi guys,

I got a new HA2100 dual core head unit.
I'm new to all that staff but i have android phone for a long time so i know many of the terms.
I installed the latest Malaysk's rom and MCU version 2.83 and i have some question and problems.
The first and major one is that after the upgrade the wifi stops work, it not start, do this related to the MCU version? do i need to downgrade the version?
second question is about the built in 'Bluetooth' app, when i get a call it appears in the bottom of the screen and i can't do anything else with the head unit, for example return to the navigation app of search for something, at least i want it not hide my navigation app, There is something to do with it?
and last but not least, there is a music player app that can play music from storage and from bluetooth device (like my phone) in the same app or at least to display the song name from the bluetooth device?

Thanks,
It's really great community!
