You can use this guide...
You can edit it directly in your phone... Use the file manager of cm13 set it to root access mode then go to /etc/snd_soc_msm you'll find it there... Then scroll down until you find the lines said in the guide
You can edit the handset by finding SectionDevice "handset"
You can use the editor of cm13 file manager
BTW... Since there's no snd_soc_msm_fusion3_auxpcm in our phone... Just ignore it and do step 1 only... Reboot after doing it...
I think the speaker can go below 74% because 74%+ is too loud and disorted
Mixer_paths.xml is a file wherein it is like snd_soc... But mixer_paths cannot be found in samsung phones and some phones... Both are the same because it is where you can find the volumes and some functions related to audio... Well mixer_paths i think is like for other phones like Nexus'
