i use the *#*#3646633#*#*and slide to the audio setting. Interestingly,  how do you have a longer list in the audio setting. In mine,  I didn't see the rest such as normal mode.

well it could be because i have older model m2 note, so idk if i can help you now, if you think it was a software issue, like i had once my gyro after update started to spin around, i fixed it with reflashing my rom with clearing data, so i suggest you to download 5.1.12.0G (if you dont have it anymore) and flash it again, with data clearing. But do remember that you should backup your data if you dont want to lose any

method for my mx5 volume sound is too low so i did this now my phone volume is clean and sound normal...try your own risk

it looks very risky as it may break the speaker. But I think your case differs with mine as you said that you could still hear the sound though it was very low.As for me no sound is audible from the speaker. Thanks for sharing, really appreciate it.
