I recently did the update and have just realized I now have no sound at all. I've checked the settings and they seem okay. There is no sound for email alerts or sending mail and worse of all no sound from videos. I know I'm weird but I don't play music from the music icon so didn't realize this till today when I tried to look at a video with sound. I always raise the sound with the toggle at the side and keep it off when not needing it. Any ideas of what has happened?
