One of my customers found a surprising work around to the Bluetooth audio failures I reported earlier. Replace the built-in Bluetooth hardware with a 3rd party Dongle that works with Apple's Bluetooth audio driver. Details are here: http://www.sustworks.com/pa_guide/btExtreme.html If you have any insight that could help get this resolved, I'd love to hear from you.

I'm seeing reports of Bluetooth SCO audio failing on some systems with an error on the console. Here's an example:

...

I am trying to use an iPhone and my MacBookAir - Lion 10.7.2 - which seems to work more or less (Phone Amgeo 1.3.3). However, on my Mac Mini, same configuration it doesn't. I can call, and monitored calls show up etc, but when I try to connect the speakerphone (i.e. computer), the console spits out an error, see below.

22/11/2011 09:53:38.000 kernel: [SendHCIRequestFormatted] ### ERROR: [0x0407] (Add SCO Connection) -- Send request failed (err = 0x0010 (kBluetoothHCIErrorHostTimeout)) 22/11/2011 09:53:38.000 kernel: REQUIRE_NO_ERR failure: 0x10 - file: /SourceCache/IOBluetoothFamily/IOBluetoothFamily-4010.4.4/Core/Family/Drivers/IOBluetoothSCOAudioDriver/IOBluetoothSCOAudioDevice.cpp:882

Any thoughts on what could be causing this?
