This started happening when I did a factory reset. The phone detects my headphones (Beats Tour); the headphone icon shows up in the notification tab and it lists suggested apps to open (Music, podcast player, etc). However, when I turn on a podcast or a music track, the sound plays through the speakers. The only way I can remedy this is to do a restart and the headphones start working. I've cleaned the headphone jack to make sure there is no lint and I've verified the headphones work on another device. I'm wondering if another app is interfering with it or if there is some sort of setting I need to use. Any help would be appreciated. Thanks.
