I haven't had my audio pause every few minutes, so I don't know if its the same issue. I use Aux in my car (the only wired "headphones" that I typically use), and it works fine when plugged in. I tested a set of standard EarPods and it works, but only alarms/timers will play out loud when I unplug them. "Headphones" appear in Control Center/Airplay menu no matter what. Most of my audio output is Bluetooth or AirPlay, unless I'm in my car, so I didn't even notice. Turned off "Hey, Siri", rebooted, hard-rebooted. Short of restoring my phone, just want to see if anyone else has this issue and any suggesting on how to fix. I don't play music on my iPhone's Speakers, but it seems like it is system-wide, affecting every app/game (which sometimes I have the volume on/up for).
