Significantly increased the sound of the speaker , but above all also fixed the microphone input/output and speaker of the call !
In other words both you and your recipient feel ALWAYS sound loud and clean like never before. The phrase " can not hear you " ( typical of someone who has a Nexus 5 ) will be only a distant memory for you .
For the following guide takes root permissions and a file manager that allows to get into the system folder (for example Root Explorer can be downloaded from playstore ) .
1) Download the file from here Best Audio Mod Nexus 5 by fosseperme V2.xml and rename mixer_paths.xml
2) Go through root explorer ( or similar) in the system folder sytem / etc and replace the file with the old one ( after making a backup of the original file of course ) . If you root explorer problems in replacing click on the top of Mount R / W ( it displays a Mount R / O) and try again.
3) Set the correct permissions for the mixer_paths.xml file before rebooting as rw-r--r-- (important to avoid bootlop)
4) Restart the phone and try to call someone! You will see the results immediately !
