Can't understand why the P905 would be any different. All Samsung devices I've had in a while have had a similar file.

I don't have it either on my SM-N9005 Note 3 or on my SM-P905 Note Pro.

Maby it's only on exynos based devices and not in SD.

Qualcomm based (mostly LTE) models have very different file structure - this is because Qualcomm provides System-on-a-chip solution including gpu/soundboard/radio devices, not only cpu, so every important component has to be configured in DIFFERENT way than elsewhere...

I haven't personally tested this, but what about opening /system/etc/mixer_paths.xml
Then finding this:

Code:
	<!-- Play Scenario  -->
	<path name="speaker">
		<path name="spk" />
		<ctl name="RX4 Digital Volume" value="83" />
		<ctl name="RX6 Digital Volume" value="83" />
		<ctl name="LINEOUT3 Volume" value="19" />
		<ctl name="LINEOUT4 Volume" value="19" />
	</path>

	<path name="headset">
		<path name="ear" />
		<ctl name="HPHL Volume" value="20" />
		<ctl name="HPHR Volume" value="20" />
		<ctl name="RX1 Digital Volume" value="77" />
		<ctl name="RX2 Digital Volume" value="77" />
		<ctl name="COMP1 Switch" value="1" />
	</path>
If I'm right, for headset "HPHL Volume" stands for left side volume and HPHR for right, and increasing these (to 25 or so??) you can increase headphone playback volume

For speakers it might be RX* Digital Volumes.

But like I said, I have not tested this so I can't know exactly what this do

Yup, been using it for a moment, even 88 seems clear and significantly louder.
Also, in the nearest neighborhood of above lines of xml file there are adjustable values for different scenarios like dock or bluetooth speaker etc.
I still recommend ViPERs audio btw

In fact I can't find any way to increase bluetooth volume (I got SM-P905). With V4A I can boost it up a little, but not enough.
More about it HERE

If you know how to increase volume max level for BT playback any help will be appreciated
