[color=#330099]I am working on an application where I have to mix 4 wav files and send to the Multi Channel card to be played in four independent speakers.
For the same I am using APIs viz. waveOutOpen and passing WAVEFORMATEXTENSIBLE structure to initialize the 4 channels of the card.[/color]
[color=#330099]I am able to open the device using this API but there is no sound played. It just makes a "chuk" noise and keeps silent thereafter.[/color]
[color=#330099]Going thru various blogs I found someone writing that Sound Blaster does not support the method.[/color]
[color=#330099]Can you please confirm me if this method is supported by the mentioned device or not?[/color]
[color=#330099]If this is not the method supported then can you please advise me the method which I can use in my case?[/color]
[color=#330099]I am new to programming multimedia and am not very familiar with other techniques available.[/color]

The only way you can make Audigy card play the multichannel singnal is through using ASIO API. Get Adobe Audition 2 it lets you work with audigy's ASIO, so you can make and play multichannel sounds. I think Cubase VST also works with ASIO quite nice.

Actually, as Audigy 2 lists and allows seting w/
- DirectSound - 4 mono output channels,
- WDM - 8 mono output cahannels and
- WDM/KS - 8 mono output channels,

this, what he's after, should be possible w/ those driver modes too.
W/ DS, it's possible that the channel output is mixed internally, so you can't get individual signals out, but w/ both WDM modes, using channels 3, 4, 5 and 6 should this all be possible (this w/ Audigy 2 which is 6.1 card) .

MME lists only 2 output channels --> no use in this task.

The card just needs to be set output to those channels (speakers setting 4/4.1 -->) and processing CMSS/EAX needs to be turned OFF.
