I had a problem with media starting and stopping, and no sound from youtube, although I had sound from ringtones, so I knew the physical speaker worked. After some research, I did a factory reset. No luck. I uninstalled all apps. No luck. So I did a 5 minute battery pull. No luck. Finally, I did an overnight battery pull = remove battery for 8 hours. Woke up, and assembled the battery to phone. My homescreen had 2 old icons that were right on right before I deleted the apps the night before. Maybe there is a buffer stack overflow in the droid deletion routine? (question for the devs). And so to continue, I started up my tunein radio and the sound and program work perfectly! Long story short, just try taking the battery out for 8 hours to fix your phone! ;-)
