Is there any way to use Bluetooth stereo audio (A2DP) in Windows 7 x64?

I have installed Windows 7 RC x64 in my laptop recently and i am not able to get A2DP working with internal Bluetooth device. I have tried downloading latest drivers from my hardware vendor but their drivers dont support A2DP. I just want to know if there is anything i can try out to get A2DP working on Windows 7 RC x64?. I did not had any such issue when i was running x86 version of Windows 7 Beta in my system, it all started after installing Windows 7 RC x64, any help regarding this will be appreciated.

I wanted to know if you have tried using Broadcom stack for Vista, I have come across many people suggesting it saying that they were able to get Bluetooth stereo audio (A2DP) working in Windows7 x64. Just check it out and let me know if it is actually helping.

So now i have tried Broadcom stack for Vista, I did not had any issue in installing the drivers but "Bluetooth Stereo Audio" is missing on x64. In my case i am having a virtual machine, if i disable the integration and install Broadcom Bluetooth stack in XP Mode than audio plays fine but not with integration feature enabled.
