Hi!
I let you here a litle tutorial how to activate earpieace as a second speaker.
Don´t hope you gonna get any super sound system... Is a very tiny speaker!

Try it at your one risk, ok?

Let´s start!
Suposing that you already now how this all works!

Pull from Vendor/etc the file mixer_paths_tashalite.xml.

Add this line under speaker lines:

Code:
<path name="earpieace">
        <ctl name="COMP7 Switch" value="1" />
        <ctl name="SLIM RX0 MUX" value="AIF_MIX1_PB" />
        <ctl name="SLIM_0_RX Channels" value="two" />
        <ctl name="RX INT7_1 MIX1 INP0" value="RX0" />
	<ctl name="EAR PA Gain" value="G_6_DB" />
	<ctl name="RX0 Digital Volume" value="86" />
 </path>
Save the file.
Now with root or in TWRP.
Copy the file to ext sd card.
Got to vendor/etc and rename de stock file as mixer_paths_tashalite.xml.bk
Copy the mod file to vendor/etc and chmod to 644 (in TWRP is easy, just select the file and you will see chmod option).

Reboot!

I must thanks to @Dante63 for his tutorial, it help me in the right way.

Check it if you noticed any change, i had to try a few times because earpiece have a low power sound, i try to rise Digital Volume above but it cut off.

See you around!
