Thread cleaned.
2.3 Flaming / Lack of respect: XDA is about sharing and this does not involve virtual yelling (flaming) or rudeness. Flaming or posting with a lack of respect is unacceptable. Treat new members in the manner in which you would like to have been treated when you were a new member. When dealing with any member, provide them with guidance, advice and instructions when you can, showing them respect and courtesy. Never post in a demanding, argumentative, disrespectful or self-righteous manner.

Thank you.

Here is the same mod, edited so that it works with LineageOS 14.1 (SM-N9005 LTE Int).

Here are the changes from the original file from the rom.
Code:
<path name="spk">
		<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
		<ctl name="SLIM RX2 MUX" value="AIF1_PB" />
		<ctl name="SLIM_0_RX Channels" value="Two" />
		<ctl name="RX1 MIX1 INP1" value="RX1" />
		<!--<ctl name="RX1 MIX1 INP2" value="RX2" />-->
		<ctl name="RX7 MIX1 INP1" value="RX1" />
		<ctl name="RX7 MIX1 INP2" value="RX2" />
		<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
		<ctl name="HPHL DAC Switch" value="1" />
		<ctl name="DAC1 Switch" value="1" />
	</path>
INP1 (left channel) goes to RX1 (ear speaker)
INP2 (right channel) doesn't to RX1 (ear speaker) [because it's commented out]
INP1 (left channel) goes to RX7 (big speaker)
INP2 (right channel) goes to RX7 (big speaker)

you can set these as you like, I found that this way, I get maximum volume, while retaining the stereo effect.

The next important lines are within Play Scenario
Code:
<path name="speaker">
		<path name="spk" />
		<ctl name="SPK Status" value="1" />
		<ctl name="HPHL Volume" value="20" />
		<ctl name="HPHR Volume" value="20" />
		<ctl name="EAR PA Gain" value="POS_6_DB" />
		<ctl name="RX1 Digital Volume" value="86" />
		<ctl name="RX7 Digital Volume" value="74" />
		<ctl name="SPK DRV Volume" value="8" />
		<ctl name="COMP0 Switch" value="1" />
	</path>
HPHL Volume, HPHR Volume and EAR PA Gain are needed so that Ear speaker starts working (I didn't hear a difference when changing EAR PA Gain to POS_3_DB, but let's say this is louder - also this setting is being used by the phone when you click extra volume in the stock rom during calling with speaker).

RX1 and RX7 set the volumes (0-100) for the Ear speaker and Big speaker, accordingly.

HOWTO:
Copy mixer_paths.xml to /etc, (backup the original), and set permissions to -rw-r--r-- (as all other permissions in the folder).
