Bluetooth audio in OSX Lion

In Snow leopard, I would use a plantronics bluetooth headset for facetime and skype chats. Now, in Lion, I can't. I keep getting a bluetooth audio error. I live in a dead zone, so this is a pretty important thing for me.

The console shows the following errors:

7/22/11 3:21:11.000 PM kernel: REQUIRE failure: mClientResponseTimedOut == false - file: /SourceCache/IOBluetoothFamily/IOBluetoothFamily-2500.4.17/Core/Family/Drivers/ IOBluetoothSCOAudioDriver/IOBluetoothSCOAudioDevice.cpp:711

7/22/11 3:21:11.000 PM kernel: REQUIRE failure: result == kIOReturnSuccess - file: /SourceCache/IOBluetoothFamily/IOBluetoothFamily-2500.4.17/Core/Family/Drivers/ IOBluetoothSCOAudioDriver/IOBluetoothSCOAudioEngine.cpp:270

I have also noticed that odd things happen to my audio as long as the device is paired, wether or not it is active. Audio is sometimes output as mono, volume controls do not work for the line out, and audio mutes (even thoguh it is shown as unmuted) at random moments. None of this can be resolved as long as the headset is paired.

Is there anything I can do to get my iMac to use the bluetooth earpiece that worked just fine in Snow Leopard?

I did download and install the latest xCode, once it is installed.

Click in the Xcode icon and open it.

In the top menu: Click on Xcode

then 'Open Developer Tools' -> 'More Developer Tools'

You will need to sign in or create an account as Xcode developer. When you sign in just type in the search field 'hardware io'.

Select and download the latest version of Hardware IO Tools for Xcode.

Once is download open the *.dmg file. In the other hand, in your application Xcode app folder do a right click and select: 'show package content'

Drag and drop all the tools from the 'hardware io' dmg file you just downloaded and place them in the 'contents->applications folder inside the Xcode app folder.

Now if you open the Xcode->Open Developers tools->Bluethoot Explorer

With Bluethoot Explorer open select from the top menu: Tools->Audio Options

I played with the options and realized that the problem was in my case with the bit rate. So I increased the number of packets that can be buffered to 50 and also the latency.

There are many bluethoot tools and graphs that you can use to troubleshoot and check where is the problem with the Xcode Hardware IO.

Let me know, with what configuration you were able to fix your problem.

Greetings.

Unfortunately, the person you addressed this to has not been active here for six years..... (and the question concerned OS X Lion which was from 2011).
