Music mutes when phone locks

[AC Question]

Every time my screen locks/sleeps my music mutes itself. Whether it's playing through head phones or the speaker, it's still muting. I've tried a bunch of different music apps and it's all the same. Phone sleeps, music mutes.

Did you ever get an answer? After the OS update (stinks, by the way), my family's phones (5 of them) randomly mute themselves, causing us to miss calls. And receiving calls is one of the most fundamental purposes of a phone.
