6.0 marshmallow - Very low to no volume after upgrade to 6.0 marshmellow

I recently upgraded to 6.0 and since then I have had very quiet volume on calls and even when listening to music.

I have everything turned up to maximum but still very quiet like it is on low.

Has anyone experienced or heard anything like this or know of some ways on how to fix this and make the volume louder?

I am also running a Droid Turbo 2.

Answer

I eventually fixed this issue with another phone replacement in the end. Apparently, it was either a glitched update or something. I opted for a free phone replacement and I've not had issues since.
