WASAPI and WMME on same application ???

[Mauro Sérgio Ferreira Brasil]

Hello there!

We develop an application here that uses OpenWengo libraries (to provide VoIP services) that, in turn, uses PortAudio.
We have just migrated it to VS2005 so we can use the new Vista audio API to configure the Microphone volume and Mute status that is not working on this S.O.

During the first analysis I noticed the presence of WASAPI implementation on PortAudio and start using it, but now I have some questions:

Question 1 - As we need to provide an application that runs on Windows 2k and newer versions of Windows, I was thinking to use WMME and WASAPI together to provide device listing and managing for all platforms at once (with WASAPI being used for Vista, and WMME for others S.O.'s).

Are these implementations mutually exclusive ?
I mean, on WinXP and priors only WMME works and I have just the devices listed by this implementation, but on WinVista I've got duplicated devices provided by both (WMME and WASAPI) implementations.
So, is there any switch to handle this situation, on such a way that Vista displays only the devices listed by WASAPI implementation and other S.O.'s display WMME listed devices ?

I've made here a control on initialization method of each implementation so the device listing is made only for the right S.O. using "GetVersionEx" method to determinate this behavior.
Is this in fact the only alternative ?

Question 2 - What is the status of WASAPI implementation ?

I'm making such a question because it is commented by default, and I've got crashes on my initial tests.
First crash was resolved with the patch provided on ticket #62, but second one will demand some thinking tomorrow... :-).

I'm working here with "pa_stable_v19_20071207.tar.gz" package provided on your site. Should I get the the "pa_snapshot.tar.gz" package instead ?

Thank's and best regards!
