Connect Mac Pro via Bluetooth to YBA-10 Yamaha bluetooth adapter.

Hi,

I have connected my Mac Pro with 13 inch screen via bluetooth to my Yamaha YBA-10 dock that is attached to my Yamaha RX-V465 amplifier to be able to listen to itunes or spotify on my speakers. I have checked forums outside this thread and found different Bitpool settings and tried to improve the sound quality, which I have done. There are some parameters that can be set. Under ~/Library/Preferences/com.apple.BluetoothAudioAgent.plist there are some parameters that are editable. I set the Apple Bitpool Min to 50 and the sound quality improved dramatically. The problem is now that after like 5 or 10 tracks that I play in itunes or spotify, the sound suddenly disappears but the bluetooth connection is still up between the devices, thus meaning Mac Pro and the YBA-10 Yamaha device. The Bluetooth connection does never disconnect, but the sound disappears? So my question is why is it so unstable. Is there other parameters that can be set like timeouts or synch to have the bluetooth connection stay up or is it just so unstable. Please need help to get the A2DP working 100%. Were is this possible to see? Need help how can I troubleshoot the problem?

Just bought a Belkin mini bluetooth adapter (from Mac Store ) and tested it, it seems like the same stuff. The sound just stops after a 5-10 tracks. When I pair with the USB adapter it flashes slowly blue, when pressing play the USB adapter starts to flash faster - the sound comes out on the speakers. Then after a 5-10 tracks the sound disappears? Sometimes I just double click on a new song and the USB starts flashing and the sound jumps to start working again? The USB is not stable either! It surely sounds and looks like a linkup/sync/timer issue in the Mac Pro profile parameter settings regarding the Bluetooth communication, cause either if I send use the inbuilt bluetooth or the external supported adapter its doing the same thing. It would be nice if Apple could fix this communication problem, it surely seems like a bug in the OS somewhere! I would be glad if this could be fixed sometime in the near future.
