[Xperia Z1 Compact General] Lessismooore:
Thanks for the mod, it's working but the sound is very distorted and the headphone is extremely loud that despite it may damage your headset, it can seriously cause some problems to your ears.

anyway I edited the original file "mixer_paths.xml" from the official lollipop in my z1 compact and adjusted the values for a high volume with clear sound without distortion...

I changed the values under these tags:

<path name="speaker">

<path name="speaker-mic">

<path name="headphones">

<path name="headset-mic">

- and for more information here is what I've done in details:

-Original speaker values:

<path name="speaker">

<ctl name="SLIM RX1 MUX" value="AIF1_PB" />

<ctl name="SLIM RX2 MUX" value="AIF1_PB" />

<ctl name="RX7 MIX1 INP1" value="RX1" />

<ctl name="RX7 MIX1 INP2" value="RX2" />

<!-- 67 % of 124 (range 0 - 124) Register: 0x2E7-->

<ctl name="RX7 Digital Volume" value="83" />

<!-- 100 % of 8 (range 0-8) Register: 0x1E0-->

<ctl name="SPK DRV Volume" value="8" />

</path>

-Edited speaker values:
