Xperia Z2 :: Headphones Not Detected

I just returned home from abroad where I was using a local sim card rather than my own. When I use a different sim card, the settings inevitably get messed up. My phone now won't recognize my headphones after Throw kicks in. What happens is that I can get music to play if I manually stop Throw. As soon as Throw restarts, the music stops playing on my headphones and goes to my external speaker. My phone won't give me the option of disabling Throw. I've tried disabling Smart Connect, disabling the headphone compatibility app, adjusting settings in throw and Smart Connect, and still have gotten nowhere after hours wasted. Losing patience.
