Can't figure out why Android Activity is pausing here

I clueless as to why my Activity is being paused right here. About 5 - 10 seconds after it starts, onPause() gets called. I just created a new blank app to debug this, and the same thing still happens. It seems to only happen on the first run after installing from Android Studio, I think. Does anybody have experience with this? I am hoping it is just something caused by Android Studio installing, and won't happen when I publish the app.

It's and instrument type app. I kinda just needed to pause the sound if the app gets paused. But now, it's just pausing so abruptly, right in front of my face.
