Music and video problems with LG G Stylo (Boost)

I've been having a problem since I got my LG G Stylo from Boost. When watching videos and listening to music using any app capable of doing so, the video or music will pause itself randomly and after a bit it will start playing again or it will play after I manually un-pause it. I'm not sure what's causing it. I know some newer and more expensive phones have features that will pause video if the phone detects that you aren't looking at it but these features usually apply to video, not music and even at that my phone doesn't seem to have that feature as I cannot locate a setting control for it. This happens in any app that can play video including videos played in Chrome and it happens in any app that is capable of music playback, which the only two I have are the native music app and Google Play Music. I've read on the internet that it could be caused by another app on my phone but I don't have any apps capable of doing this. I've also read that this can happen when switching networks but my phone is on WiFi most of the time and only switches to 4G when leaving the house which isn't that often. I don't see any reason why this would be happening. I've never had this problem with any other phone and I don't really have any apps on this phone that I didn't have on my last phone. Note that this is my first phone running Lollipop (5.1.1) and I'm starting to think that Android itself is the culprit but I'm not sure. I recently rooted my phone but the problem existed before that and I had the phone for over a month before I attempted root. This is really annoying and I'd like to be able to fix it so anything helps, thanks.
