Openmax AL implementation on windows 7


I am pretty new to OpenMAX and would like to experiment few samples based on openmax AL. Please help me identifying any open souce project available which uses openmax AL implemented supporting windows 7 platform.
I found few implemenatations on linux platform( namely bellagio) but unable to find any such implementations on windows till now.
Kindly help me out on this request.
Thanks in Advance
