DIrectSound on top of openAL ?

[Jérôme Gardou]

I was wondering why directsound was not implemented using openal. As 
direct3d is implemented on top of opengl.
I see three major advantages :
openAL is cross-platform, whereas alsa is linux-specific.
openAL is (sometimes) hardware-accelerated.
Wine would bring directsound hardware acceleration to windows vista :) 
See 
http://connect.creativelabs.com/openal/OpenAL%20Wiki/OpenAL%C2%AE%20and%20Windows%20Vista%E2%84%A2.aspx
for manufacturers which bring hardware accelerated openal drivers...

Plus, wine would benefit of the system's openal configuration. No need 
to chosse between OSS and ALSA, the user would have done it through his 
openAL configuration.
