I've searched the forums but was unable to find info to address my questions. I have a Motorola S9 Bluetooth headset, supporting A2DP, but am not having any luck in getting sound from all sources to go to the headset. For example, Youtube sound continues to play through the Droid's speaker. And just recently, I can no longer get my music to play through the headset. Phone calls continue to work through the headset fine, but that is about it. I have only downloaded a handful of applications, and don't "think" they would impact this area, but an open question I need to do more research on. How can I determine if there is a good connection from the phone to the stereo headset (ie. mono only, A2DP, etc)? Within the Bluetooth settings, I have "Connected to phone audio" under the Motorola S9 device, but am not aware of any other settings that I need to set or could have changed to affect the music. I have reviewed both S9 and Droid owners guides with no luck either. Any help or pointers would be greatly appreciated.
