So after noticing the new app icon for the FM app in nougat I decided to give it a look. I listened to radio through my speakers AND my headphones and then exited the app to watch YouTube.
All of the dialogue in the videos are muffled but background music and other songs are just fine. This is also the problem in Google play movies.
I'm certain its the FM radio app messing with equalization. How do I fix this or reset audio settings? I've tried force stopping the FM app as well as disabling it (can't uninstall because it's a default app)
