How to increase speaker/call volume? (cm11.2) Sometimes after I install new version of cm speaker volume is too low. Then I install another version and it is ok. I did some search and found this post (http://forum.xda-developers.com/showthread.php?t=2400231)  describing how to fix that for Samsung.

The exact line I you need to edit is RX5 Digital Volume:1:65% but I did not find that one in my 'snd_soc_msm_2x' config file.

Any one could explain how to fix the volume for HTC One XL? I do not want to install any sw to make this work. 

Currently I am running 11-20150104-nightly and the volume is very much too low. My snd_soc_msm_2x looks like

Code:

EnableSequence
    'SLIM_0_RX Channels':0:eek:ne
    'RX3 MIX1 INP1':0:RX1
    'RX4 DSM MUX':0:DSM_INV
    'LINEOUT1 DAC Switch':1:1
    'LINEOUT3 DAC Switch':1:1
    'LINEOUT1 Volume':1:73
    'LINEOUT3 Volume':1:73
    'RX3 Digital Volume':1:73
    'RX4 Digital Volume':1:73
    'SPK AMP EN Switch':1:1
EndSequence


The original steps how to fix it from the link above are....

Code:

Navigate to device folders.
Open "etc" folder.
Open "snd_soc_msm" folder.
Open file "snd_soc_msm_2x" file with editor.
Look for the following section below, it is at 41% using ES editor.

SectionDevice
Name "Speaker"
Comment "Speaker Rx device"

EnableSequence
'PRI_RX Channels':0:Two
'RX5 MIX1 INP1':0:RX1
'RX5 MIX1 INP2':0:RX2
'RX6 DSM MUX':0SM_INV
'LINEOUT2 Volume':1:100%
'LINEOUT4 Volume':1:100%
'RX5 Digital Volume':1:65%
EndSequence

The exact line you want to edit is
'RX5 Digital Volume':1:65%

Only change the percentage amount, and only change it in small increments
I'm thinking your phone is codenamed "evita" and the file you're looking at is here.  Maybe you could try kicking up those ":1:73"s to ":1:78" or another small increment, restart, and see if it's any louder.  If so, raise the number from 78 to 83 or whatever until you find the volume you like.

You can compare with this change for mako (Nexus 4) and this comment as well...  You might also Google for "msm8960 volume" to see recommendatiosn for other devices that use your qualcomm system-on-a-chip. 

I don't know for sure if this will work as expected, but you can report back and let me know if it does.
