I first noticed this when sending Snapchat videos/posting stories. About 2 or 3 seconds after I start recording the sound will drop out momentarily and then resume. I thought this was just a glitch with Snapchat seeing that video quality already sucks on Android and just figured it wasn't a big deal. However, after a few updates to the app I was still experiencing the same problem so I thought to check to see whether it happened when I recorded video with the default camera app. Alas, a few seconds in the audio cuts out for a moment and then resumes. After searching Google and trying to find answers/similar reported problems on here and other Galaxy S4 forums, I've come up with nothing (most problems relate to either the audio not playing at all or the video cutting out while the audio continues to play).
For reference, I have an AT&T Galaxy S4 with Android 4.4.4.
