I just posted a questions about not being able to hear audio on my Samsung Galaxy 3. (could hear phone calls). I thought I'd post the solution. I had paired my wireless earbud with the phone through bluetooth. When I clicked on the bluetooth setting, I saw that "calls" and "media" were both checked, which meant they would both be heard through my earbud. When I unchecked media. I could hear the audio (without the headset). Unfortunately I could not post this as a reply on my original question because I didn't have a login but hope this helps!
