multiple sound cards
Author
hi everyone
I'm developing an aplication that needs to use multiple sound devices at the same time, I search several websites and googled for a few hours trying to find a solution and I didn't find anyting
being able to change the device would also work, but using both would be great
any ideas?
thanks in advance
edit:
oh ya and it's for win xp

that was a fast reply :)
well it's a simple voip phone, using sip messages
I'm using C# and the OS is win XP
not using any API, just the .net framework soundPlayer

DirectSound should allow opening multiple devices without a hitch. OpenAL should also handle multiple devices.

I'll be killing a bug with a bazzuka using those :D
I'll check out the DirectSound
know any websites with examples? I never used those

Are you already using multiple sound cards?
Last time I put two sound blasters on the same PC the driver went crazy and took quite a while to go back to a predictable state.
Please, give me good news!

and actualy it's not 2 sound cards, it's a onboard sound card and an usb phones
I'll post the code here once I'm done

ok I have a small problem
the sound works fine but when I minimize my Form the sound stops
I know this is suposed to happen, but is there anyway around it?
also find something about using Microsoft.DirectX.AudioVideoPlayback, but I can't find it
any ideas?
thanks in advance
