A number of us have been trouble shooting issues with audio application randomly stopping and sometimes starting. I been able to replicate this an LG3, Note4 and Note7. It is happening on Android version 6.0.1. Problem occurs across mulitiple music players I have tested including Google Play, Samsung Play and black player.
After may tests the only thing that stops the issues is when I elliminate xfinitity connect app. Others reporting somethng similar. It would be nice if comcast could look into this and provide a fix. Until then I will unfortunately be uninstalling my xfinity apps.
Notes from others:
Confirmed this on my Android running 7.1. Connect app breaks google play music app, resulting in random pause/stop events. Uninstalled the connect app and issue goes away.
