hi, i'm listed as battery expert in first page so i must help you 

audioout_2 refers to any sound or audio generated while the screen is off. Eg: listening to music while screen is off will increase audioout2 wakelock. wakelock refers to any time the cpu is not sleeping but the screen is off, so it satisfies that condition. It can also be caused by notification sound, sms sound, lock screen sound, etc. 

audioout_1 or 3 instead refers to an app that is causing the wakelock even if no sound is playing.

example: i found out neutron player causes audioout_1, how i determine? i noticed in BBS the audioout_1 is increasing in duration each time i off my screen, i knew it is an app causing because no music was being played, i check my running processes in settings>general>apps>running processes and found out neutron player is running.

here i either try to fix the problem by changing the app's settings or i uninstall it straight, i couldn't fix it with the latter so i uninstall it and problem solved.

generally if audioout_2 is less than 30 mins it is normal.
