iOS 8.4 Audio Bug

Anybody else experiencing an odd bug in iOS 8.4 where audio starts playing at random times? So far it has happened to me when switching between apps, or when locking/unlocking the screen, but not every time. The source of the audio can be either the Music app or a podcast player. It can make for some embarrassing situations, like when using the phone in a quiet office environment and all of a sudden Beats One comes blazing out of my speakers because I locked the screen.
