Why is my Samsung Galaxy S4 playing sound from the front speaker?

[AC Question]

Hi there,

Ever since updating to Android Lollipop, my Samsung Galaxy S4 is for some reason playing all sounds from the speaker at the top on the front of the phone, and not from the speaker on the back. Any ideas as to what may be causing this? Quite annoying as I can't hear my alarm going off in the morning!

Thanks
Andrew
