Problem raised: Mid-Oct 2010
Problem solved: 2 Jan 2011
Solution type: unofficial solution
Description: I have bought a Plantronics Voyoger Pro for use with skype on mac at around august 2010, it worked very well until around October when it suddenly unable to input/output audio signal. It is still able to pair with the bluetooth module on mac, but when i try to play any sound from my mac, i am not able to hear any sound from the headset, and the beach ball appears on the mac, with some applications becoming unresponsive.
Causes: the Mac OSX 10.6.5 update includes an update for the bluetooth audio agent, with makes some bluetooth headset unusable with mac
Solution: rollback the bluetooth audio agent to an earlier version
1. locate the current bluetooth audio agent(BluetoothAudioAgent.app) in “/System/Library/CoreServices/”, My current version is 2.3.8.
2. Get a previous version of the BluetoothAudioAgent.app and replace the current file on your mac, my previous version was 2.3.3. You can get the previous version of the file from either one of the following ways.
a. here
b. Your time machine backup
c. MacOSX Installation disk (Get Pacifist to browse the package content of the disk, and find the BluetoothAudioAgent.app from the package contents)
3. Try to delete the bluetooth device and pair it again, it should work like what it did in the past!
