No sound from speaker for 'most' apps like Music, Pandora, GamesMy iPhone 4 won't output sound from the speaker for 'most' apps like the Music (formerly iPod app) app, Pandora, and YouTube....
Answer to: No sound from speaker for 'most' apps like Music, Pandora, GamesOkay, I got my iPhone fixed by a 3rd party shop, not Apple. Turns out it was the dock connector. I had that replaced and now my iPhone 4 speaker works fine. Even my unresponsive home button problems went away. (I don't know why but it did.)
