When I play audio from my Galaxy S4 (Lollipop) to my bluetooth speaker, I often get hiccups in the audio playback. These are delays rather than dropouts because I lose the beat when they happen. Sometimes they can last a few seconds. They occur with at least three apps (Spotify, Songsterr and Soundcloud). When I play music through the headphone jack I get the occasional hiccup, but not nearly as bad or frequent as the ones I get with bluetooth. How can I stop these Bluetooth hiccups?
