Hi guys. Sorry I posted this thread without registering and literally forgot where I posted. The problem happens when playing MP3 files using Jet Audio and 2 random MP3 players just to double check. Also on Youtube. On the speaker phone, in landscape mode, the right side is louder, but when I flip the orientation the problem speaker is still the same speaker. In other words, one way the right speaker is louder, and when I re-orientate it, it is the left speaker that is louder. This isn't exactly the way it is when playing stereo sounds. When playing stereo sounds, it is always the right speaker that is louder regardless of orientation.
BTW Motorola is advance shipping me a new phone as they said this isn't normal. But in the meantime I have been tinkering with this phone. I did discover something that caught my attention. In /system/etc/mixer_paths.xml there are a few lines that looked odd to me. I backed up the .xml file and tried to edit it in ES Explorer using ES Note Editor and QuickEdit in order to set both boost values to 2. It won't allow me to save the file saying "Error occured... No enough space!" (yes it said "NO" enough space). I tried my heart out to figure out how to save the edited file using CHMOD in both ES Explorer and TWRP with no luck. I am thinking this may be the problem.
Now I am pretty much a complete noob with Android, so please don't use any bog words, but I am a pretty curious person. BTW the headphone jack is totally fine and plays stereo with equal balance.
edit: Phone is rooted and I am using N6.ElementalX.3.0 Android version 6.0.1.
