[Openal] 5.1 Surround sound under MS Vista and openAL

[Benoit Hamet]

Hi all,

I'm trying to test openal for internal usage with surround sound. After
playing with the configuration I finally managed to get my 5.1
configuration working (I test it with the multichannel audio sample
played by WMP given in the media directory of the OpenAL SDK Samples).
But when trying to test it with the tools given by openAL, (ie the
playMultichannelSample), then the sound is only in 2.1.

Does some of you have ideas on what is going ? I try to look into the
mail archive of openAL, digging around take a look  in the DirectSound
systems (was hopping to find how to configure it for 5.1 systems), but
no luck.

OpenAL come from Creative Labs site, The sound card is an onboard one
(so when enumerating it's recognised as a Generic Card with 256
channels), and Windows vista is the professional version.

Thanks in advance for your help.

Regards,

Benoît.
