Stereo Bluetooth Profile (A2DP) on Mac OS X Tiger with Jack Audio

The tutorial below is outdated and should not be attempted. 
If you want A2DP, upgrade to Leopard. 

Low latency Stereo Bluetooth Audio is now possible on tiger thanks to Tim Hewett's a2dpcast which uses Jack for recording from the system mixer or indeed any specific coreaudio application.

To use the new system:
  1. Download Jack for Mac OS X from here.
    Make sure to read the documentation on how to install properly on Intel Macs, especially making an Aggreagate Device with "Audio Midi Setup". For the exact proceedure watch the screencast at the bottom of this post.
  2. Download a2dpcast from Tim's website, here.
  3. Extract and copy to /usr/local/bin
  4. From a terminal run
    a2dpcast ADDR
As it's based on the bluetooth code in the previous instructions, please continue to post compatiblity experiences, here.

N.B. The old instructions posted on this blog are now obsolete!

Update: Improved compatibility with new version from Tim with special thanks to Paul Guyot.

Hey guys, so I finally got sound coming out of my BT3071 Kensington headphones but it's really very choppy and drops out often. I can hear the music playing through them but there is a frequent buzzing sound and static. I have combed the comments on this blog through and through and noticed a few parts that mentioned lowering the quality or changing the channel. Could someone tell me how to go about doing that? I'm using the a2dpcast version 3 with the kext thing. Thanks a bunch.

I used asae's method with /usr/local/bin/a2dpcast YO-UR-HE-AD-SE-T 27, and it works w/ Jawbone's Jambox, on an my PowerBook G4 10.4.11.
WOWOWOWOWOWOW. Great (stereo) sound.
(Mono sound until I added the 27 as Tim Hewett suggested)
Thanks again.
