New Bluetooth Earbuds Sound Issues, Redmi 4g Note

[aironitzi]

Hello,
recently i bought Plantronics BackBeat Go 2 bluetooth Earbuds, and i tried them with my REDMI 4G Note with ROM xiaomi.eu_multi_dior_5.5.1_v6-4.4.
The Sound Quality is pour, it has a "noisy metalic Sound", just horrible. Then i bought a Bluettoh Adapter, from 3,5" jack to bluethooth, then the sound Quality is perfect.
So i sopouse that somthing happens with the Bluetooth Drivers or some *.conf is wrong.

Thnx

After days of research in google i get the solution!
My Mobile Data: REDMI 4G Note Weekly ROM 5.6.4
You need a rooted device, the weekly ROM is default rooted, you have to give root acces to any File Explorer under "Security/Permission/Root Access"
Dowload One Plus One CM 11 ROM from here, i downloaded the newest one. But i think you ok with any of CM One PLus One Rom.
Make backup of your Original Files before trying this if something goes wrong.
In the downloaded *.zip. Copy "bluetooth.default.so" and "audio.a2dp.defualt.so" from directory "\system\lib\hw" into your Phone same path /system/lib/hw.
Now restart the Mobile and enjoy the Normal Sound of your Headsets.

A shame that the Developper Team Ignore this big Issue! Not only here in the Inofficial also in the Official site.
