[Galaxy S 5 General] fbs:
These are the values I changed in my 900m (AOKP) rom...

Both the internal and the headphone mic was low for video calls or recording in general.

Everyone can simply edit this text file and alter the values. It's located at "/system/etc/mixer_paths.xml"

- = original values

+ = my modified ones
